When dividing by multiples of 10, you can easily figure out a solution without a calculator by simply moving the decimal left (depending on the number of zeros). For example:
9.63 divide 100
There are two zeros in 100 so you move the decimal two places to the left:
Multiplying fractions is simpler than you think. To multiply fractions, simply multiply across. Think is 6 as being 6/1. Also, remember, fractions are just like dividing: 9/3 is the same as 9 divide 3.
6/1 times 4/6.
First, multiply 6 and 4 to get 24.
Next, multiply 1 and 6 to get 6.
Your answer is 12/3 (to get this, you "simplify" it. They're both even numbers and so, you divide them by 2 to make it simpler) but however, remembering that fractions mean division, you get 4 (12 divide 4).
