Percentages, Fractions, and Decimal Values

To round 4.76 to one decimal place, you look at the digit in the second decimal place, which is 6. Since 6 is greater than or equal to 5, you round the first decimal place (7) up by one. Therefore, 4.76 rounded to one decimal place is 4.8.

75% of 5,000
= 75% * 5000
= 0.75 * 5000
= 3,750

When multiplying a number with decimal places to the hundredth (2 decimal places) by a number with decimal places to the tenths (1 decimal place), the total number of decimal places in the product is the sum of the decimal places of both numbers. Therefore, the product will have 2 + 1 = 3 decimal places.

Half of four fifteenths is calculated by multiplying four fifteenths by one-half. This can be expressed as (\frac{4}{15} \times \frac{1}{2} = \frac{4 \times 1}{15 \times 2} = \frac{4}{30}). Simplifying (\frac{4}{30}) gives (\frac{2}{15}). Thus, half of four fifteenths as a fraction is (\frac{2}{15}).

To find what is 21 hundredths more than 4.044, you can convert 21 hundredths to decimal form, which is 0.21. Adding this to 4.044 gives you 4.044 + 0.21 = 4.254. Therefore, 21 hundredths more than 4.044 is 4.254.

Three twentieths, represented as the fraction ( \frac{3}{20} ), cannot be simplified further because 3 and 20 have no common factors other than 1. Therefore, ( \frac{3}{20} ) is already in its simplest form.

To find 30 percent of 301, you multiply 301 by 0.30. This gives you 90.3. Therefore, 30 percent of 301 is 90.3.

To find out how many fiftieths are equal to three tenths, you can set up a proportion. Since three tenths (3/10) can be converted to fiftieths by multiplying by 5 (because 10 times 5 equals 50), you get (3/10) × (5/5) = 15/50. Therefore, three tenths equals 15 fiftieths.

Safety belts increase your chance of surviving a collision by more than 50 percent. They are designed to restrain occupants in their seats, reducing the risk of serious injuries by preventing ejection from the vehicle and minimizing movement during a crash. Wearing a seatbelt is one of the simplest and most effective ways to enhance safety on the road.

To simplify the ratio of 10,000 to 100, you divide both numbers by 100. This gives you 100 to 1. Therefore, the simplified ratio of 10,000 to 100 is 100:1.

To find what percent 10,800 is of 12,000, you can use the formula: (part/whole) × 100. Here, it would be (10,800 / 12,000) × 100, which equals 90%. Therefore, 10,800 is 90% of 12,000.

Percentage = 81%

Decimal = 0.81

Fraction = 81/100

NB Notice how the numbers are displayed in each case.

One percent of R16,000.00 is calculated by multiplying R16,000.00 by 0.01. This equals R160.00. Therefore, 1 percent of R16,000.00 is R160.00.

To find 65 percent of 3180, you multiply 3180 by 0.65. This calculation gives you 2077. Therefore, 65 percent of 3180 is 2077.

The two decimals equivalent to 0.90 are 0.90 itself and 0.9. Both represent the same value, as trailing zeros do not change the numerical value of a decimal. Another equivalent decimal could be 0.900, which also maintains the same value.

To find 800 at a rate of 8 percent, you multiply 800 by 0.08 (which is the decimal form of 8 percent). This calculation gives you 64. So, 8 percent of 800 equals 64.

Twenty-two and eighty-seven thousandths is written as 22.087 in decimal form. The "twenty-two" represents the whole number part, while "eighty-seven thousandths" indicates the fractional part, which is 87 divided by 1,000.

A decimal number and a thumbtack both represent precision and stability in their respective contexts. A decimal number provides exact values in mathematics, allowing for precise calculations, while a thumbtack secures items in place, ensuring stability and order. Both serve as tools for organization—one in numerical representation and the other in physical space.

The 5 in the thousands place represents 5,000, while the 5 in the tens place represents 50. To find how much greater the 5 in the thousands is than the 5 in the tens, subtract 50 from 5,000, which equals 4,950. Thus, the 5 in the thousands is 4,950 greater than the 5 in the tens place.

Seven tenths of one meter is 0.7 meters. This can also be expressed as 70 centimeters, since there are 100 centimeters in a meter. Therefore, 0.7 meters is equivalent to 70% of a meter.

To determine how much 30 percent is in grams, you need to know the total weight you are calculating from. For example, if you have 100 grams, then 30 percent would be 30 grams (30% of 100g = 30g). If the total weight is different, simply multiply that weight by 0.30 to find 30 percent in grams.

Food grade paraffin wax is generally considered safe for use in food applications, but when burned, it can release potentially harmful substances. Soy and beeswax are often recommended as safer alternatives for candles, as they burn cleaner and produce fewer toxins. If you prioritize health and environmental considerations, opting for soy or beeswax candles is advisable. Always ensure proper ventilation when burning any type of candle.

To divide a number by 1000, you move the decimal point three places to the left. For example, if you have the number 5.67 and you divide it by 1000, you would move the decimal to get 0.00567. If there aren't enough digits to move the decimal three places, you can add zeros as needed.

Achieving 100 percent efficiency is impossible due to the inherent limitations imposed by the laws of thermodynamics, particularly the second law, which states that energy transformations always result in some energy being lost as waste heat. Additionally, real-world processes involve friction, resistance, and other forms of energy dissipation that prevent complete conversion of input energy into useful work. Even in idealized systems, factors such as material imperfections and external influences introduce inefficiencies. Thus, some energy is always lost in any real process, making 100 percent efficiency unattainable.

About 25 percent of a fresh apple's volume is made up of air. This air is trapped in the cells of the apple's flesh, contributing to its crisp texture and buoyancy. The presence of air also plays a role in the apple's overall flavor and freshness.
