Numbers

A rational number is a number that can be expressed as a ratio of two integers. In this case, 2.645 can be expressed as 2645/1000, which simplifies to 529/200 when reduced to its lowest terms. Since 529 and 200 are both integers and the denominator is not zero, 2.645 is a rational number.

Oh, dude, you're really making me do math right now? Fine, fine. 7854308 rounded to the nearest ten thousand is 7850000. There you go, hope that satisfies your burning desire for precision in the realm of large numbers.

Three hundred and thirty thousand written in words is "three hundred thirty thousand." This number is composed of three parts: three hundred (300), thirty (30), and thousand (000). When combined, they form the numerical value of 330,000.

To write 7.9 in words, you would write "seven point nine." This indicates that the number 7 is followed by a decimal point, and then the number 9. This format is commonly used to represent decimal numbers in written form.

Numbers that round to 80 are those that fall between 75 and 84. When rounding to the nearest ten, any number 75 to 84 will round to 80. This is because the midpoint between 75 and 84 is 79.5, which rounds up to 80. Therefore, the numbers that round to 80 are 75, 76, 77, 78, 79, 80, 81, 82, 83, and 84.

Roman numerals XL is 40, and LX is 60. Numbers in-between are XLI, XLII, XLIII, XLIV. XLV, XLVI, XLVII, XLVIII, XLVIX, L, LI, LII, LIII, LIV. LV. LVI, LVII, ;LVIII, and LVIX.

To write the number 1,500,000,000 in word form, you would say "one billion five hundred million." This number is composed of three groups of three zeros, which correspond to "billion," "million," and the base unit "one." The prefix "bi-" denotes two groups of three zeros, while "mil-" denotes one group of three zeros.

The numbers 31, 37, 41, 43, 47, 53 and 59 are prime.

Round 12.7 to the nearest whole number would be 13. When rounding a number, you look at the digit immediately to the right of the place value you are rounding to. If that digit is 5 or greater, you round up; if it is less than 5, you round down. In this case, since the digit to the right of the tenths place is 7, which is 5 or greater, you round up to 13.

To write the decimal number 25.2 in words, you would write "twenty-five point two." The whole number part, 25, is written as "twenty-five," and the decimal part, 0.2, is written as "point two." This follows the standard convention for expressing decimal numbers in written form.

An even number is one that when divided by 2 gives an integer. Now this questions becomes which is smaller, 0 or negative numbers. The number -2 is even since 2 divides it integrally. Is -2 less that 0? Many people say a number A is smaller than a number B is A is to the left of B on the number line. Certainly, that would make -2<0 and zero would not be the smallest even number. When we evaluate absolute value of 0, then we say that 0 is the smallest even number in the absolute value. Really, we don't know what is the smallest number but we say that - ∞ is a value smaller than any fixed bound, so we can't say exactly which is the smallest even number.

1/5 of 105 = 21

Oh honey, it's simple math. When you square a negative number, you're just multiplying it by itself. So if you square -5, you get 25. It's like taking a negative and turning it into a positive with a little math magic.

Pi is not the biggest number in the world, just one of the longest.

It shares that honor with all the other 'repeating' or 'recurring' decimals. These are decimals that go on into infinity and never stop.

0.0007 in word form is seven ten thousandths, or zero point zero zero zero seven.

Oh, isn't that a happy little question? If we take a look between 80 and 85, we find the number 82 nestled right in the middle, like a little bird perched on a branch. It's a peaceful number, just waiting to be noticed and appreciated.

Oh, dude, you want a math working model for class 11? That's like asking for a unicorn at a pet store! But hey, you could make a cool model showcasing different geometric shapes or maybe demonstrate a math concept using everyday objects. Just remember, it's all about having fun with it, not stressing out too much.

There are 21 integers between 0 and 20, inclusive. This is because when counting the integers between two numbers, you need to include both endpoints in the count. So, in this case, you would include 0 and 20 in the count, resulting in a total of 21 integers.

Oh, what a lovely question! To write the number 90,000,000 in words, you simply say "ninety million." Just imagine all the happy little zeros dancing together, creating a beautiful number that brings joy to our hearts. Remember, there are so many ways to express numbers, and each one is a unique opportunity to spread positivity and creativity!

100 duotrigintillion.

For such large numbers, I suggest you convert them to scientific notation.

Oh, dude, like, obviously 425 is the odd one out. I mean, come on, even I can see that, and I'm not even trying. It's like the black sheep of the group, standing out all awkward and alone.

In decimal form, 0.12 is smaller than 0.2 because the digit 1 is less than 2. When comparing decimals, you start from the left and move to the right. The first place where the digits differ determines which number is greater. In this case, 0.12 is smaller than 0.2 because 1 is less than 2.
