A Prime Number is a number that can only be divided by itself and 1.

A recurring decimal is a decimal that goes on forever. (3.333333333333 recurring is a recurring decimal because it has no end)

A terminating decimal is a decimal has an ending. (So 1.2 is a terminating decimal because it stops)

LCM stands for lowest common multiple.

This is the lowest multiple that two numbers share.

eg. the LCM of 2 and 5 is 10.

Multiply the numbers as if they aren't decimals. (3.4 x 5.3 would be 34 x 53) Then count how many numbers there are behind the decimal point. ( In this case, there are two decimal points.) Then place the decimal point the number of places behind the two numbers. ( So the answer would be 18.02)

1. Multiply the top numbers (the *numerators*).

2. Multiply the bottom numbers (the *denominators*).

3. Simplify the fraction if needed.

Example:

2/3 X 2/5 =4/15

Step 1. Turn the second fraction (the one you want to divide by) upside-down | ||

Step 2. Multiply the first fraction by that reciprocal Step 3. Simplify the fraction (if needed) |
