What else can I help you with?
Can you divide mm figures by 100 to change directly to decimeters?
You must multiply millimeter figures by 100 to change to decimeters.
HOW TO CONVERT CENTIMETER TO METER?
There are 100 centimetres in 1 metre. Therefore; 1 centimetre equals 0.01 metre or 1/100 meter. So in order to convert 'x' units of centimetre(s) to metre, you must multiply 'x' by 0.01 or divide 'x' by 100.
Do you see any differences from an equation when you add or subtract numbers to both sides of the inequality sign?
No, the process is exactly the same. However, when you multiply or divide, you must be careful: if you multiply or divide by a negative number, the direction of the inequality must be changed, for example: -x + 3 > 15 (multiply by -1) x - 3 < -15
How do you divide multiply add subtract fractions?
for subtracting fractions you must find a common denominator. For example 4/6 -1/3 then you must either multiply 1/3 by 2 or divide 4/6 by 2. Id you choose to multiply then you get 4/6 - 2/6 and then you just subtract 4 and 2 and leave the common denominator out of this. the answer to this question is 2, them you add the denominator to make it 2/6. Then you should put it into lowest terms. In this equation you can divide by 2 to get 1/3. To multiply you must cross reduce then multiply the denominator and the numerator. And then you will get you answer
What do you notice about the answer you get when you divide by 1 over 4 or multiply by 4?
answer is the same
Can you divide mm figures by 100 to change directly to decimeters?
You must multiply millimeter figures by 100 to change to decimeters.
When changing from smaller units of length to larger units of length you must multiply or divide?
You must divide.
What must occur in a linear inequality when you divide or multiply by a negative number?
The inequality sign must be flipped.

What are the properties in solving equations and inequations?
You can add, subtract, multiply, or divide both sides of the equation or inequality by the same number. Don't multiply or divide by zero. In the case of an inequality, if you multiply or divide by a negative number, the sign of the inequality must be reversed. E.g., if you multiply both sides by -2, a "less-than" sign should be replaced by a "greater-than" sign.
When you must reverse the inequality sign?
When solving an inequality, you must revers the inequality sign when you multiply (or divide) both sides by a negative number.
Why do you have to multiply or divide both the numerater and denominator of a fraction to find an equivalent fraction?
Whatever you multiply or divide the numerator by, you must do the same to the denominator. If you multiply or divide the numerator and denominator by different numbers, you change the value of the fraction and turn it into a different number. After that, nothing is "equivalent" any more ... you're working with a changed number.
What must you do when you multiply or divide each side of an inequality by a negative number?
When you multiply or divide each side of an inequality by a negative number, you must reverse the direction of the inequality sign. For example, if you have ( a < b ) and you multiply both sides by a negative number, the inequality changes to ( -a > -b ). This reversal is crucial to maintain the correct relationship between the two sides of the inequality.
What must multiply or divide by to convert SI units?
To convert SI units, you typically multiply or divide by powers of ten, which are represented by the metric prefixes (e.g., kilo- for 10^3, centi- for 10^-2). For example, to convert from meters to kilometers, you divide by 1,000 (or multiply by 10^-3). Conversely, to convert from millimeters to meters, you multiply by 0.001 (or divide by 1,000). This system allows for straightforward conversions within the metric system.
