you multiply when you see this x

You know when there are key words like times, each, and in all

With these two numbers you can either divide or multiply! If you multiply you would do 12x15=180! Or you can divide instead! All, you have to do is divide 12 into 180 and you would get 15! Both of these solutions are so easy if you just work them out! i hope this answer helped you understand!

Take the area, divide by pi, get the sqare root of that number, multiply by 2, multiply by 3.14

U multiply then divide who am I kiddin I dont know this

In the sequence 20 5 30 6 42 7, the rule is divide by 4 then multiply by 6, divide by 5 then multiply by 7, divide by 6 then multiply by 8 since each time the number by which you multiply or divide by increases by 1. Since the last multiplication was by 7, we know the next will be by 8. Therefore, the answer you get for the next number in the sequence is 56 (7x8=56).

You multiply the height and base then divide by 2.

Divide the new number by the percentage and then multiply the answer by 100

You need to know the base and height of the triangle. Once you found these multiply together and divide by two.

Because otherwise you would only know how to subtract and add with the same integers. Not a particularly useful skill unless just those integers turned up!

24. If you don't know already, to multiply a number and a fraction, take the number, multiply it by the top, then divide the bottom.

multiply V by 3 then divide by 4pi , find the cube root of this, then square it and multiply by 4 pi

Divide The number of yards in a mile (1760) is a constant and is determined by the definitions of yard and mile. It is not something that you can find out by computing, If you want to know how many yards a certain number of miles is, you would multiply by 1760. If you want to know how many miles a certain number of yards is, you would divide by 1760.

Integers are simply "whole" numbers such as 0,1,2,3 and so forth (as opposed to 1.5 for instance). To multiply integers we either have to know our times tables or know how to make use of a computer. To know both is preferable.If, as an absolute minimum, you learn the times tables for all the 10 digits (up to and including times 9 for each one) then you will be able to multiply any two integers (within practical limits). In fact you will be able to multiply any 2 rational numbers. You might need to use a pen and paper but, given enough time, you could do it.Otherwise, you can use a computer (such as a calculator) to do the work for you. Of course, one should not solely rely on computers and should be able to make calculations, such as these, unaided when required.The only other piece of information you need to know for the multiplication of integers is that whenever you multiply two numbers with the same sign (i.e. two positive or two negative numbers) the result will be a positive number. Whenever you multiply two numbers with different signs (i.e. a positive and a negative number) the result will be negative.

You must know how to add, subtract, multiply and divide by some fractions.

You put 83 over 100, the percent you want to know, then you put 813 across from it on the bottom, with a line over it and a blank over 813. Then you cross multiply and then divide. So you multiply 83 times 813 and divide by 100 and that is your answer.

There are 5,280 feet to a mile. Thus: ---If you know feet, divide by 5280 to get miles ---If you know miles, multiply by 5280 to get feet

First, divide your answer by 2 Next, divide that answer by 3.14 Then, multiply that answer by 2 there's your answer
