LET'S GO!!!

## Multiplying Fractions

## If you want to divide fractions, you need to know how to multiply fractions.

## STATE THE PROBLEM state the problem. If you have a mixed number, turn it into an improper fraction. Our problem is 2/3 x1/6. Always remember that in word problems, you need to say the problem out loud. If you hear yourself saying "of", then it is a multiplication problem. | ## SIMPLIFY See if you can simplify. But remember that when you simplify before you multiply fractions, you simplify diagonally. Than adjust the problem after. If you can't simplify, then move on to the next step. | ## MULTIPLY multiply the numerator with the numerator and the denominator with the denominator. Look at your problem. Are you done? Can it be simplified even further? Into a whole number? If you changed a mixed number into a improper fraction, remember to convert it back! |

## STATE THE PROBLEM

state the problem. If you have a mixed number, turn it into an improper fraction. Our problem is 2/3 x1/6. Always remember that in word problems, you need to say the problem out loud. If you hear yourself saying "of", then it is a multiplication problem.

## SIMPLIFY

See if you can simplify. But remember that when you simplify before you multiply fractions, you simplify diagonally. Than adjust the problem after. If you can't simplify, then move on to the next step.

## KEEP IT-DIVISION Keep the first fraction the same. If any of the fractions are mixed numbers, than convert them into improper fractions. | ## CHANGE IT-DIVISION With fractions, division is basically multiplication. So, change the division sign into a multiplication sign. | ## FLIP, SIMPLIFY AND SOLVE IT-DIVISION Flip the last fraction around to it's reciprocal. Simplify the problem then multiply. Dividing fractions is really as easy once you get the hang of it! |

## KEEP IT-DIVISION

Keep the first fraction the same. If any of the fractions are mixed numbers, than convert them into improper fractions.

## CHANGE IT-DIVISION

With fractions, division is basically multiplication. So, change the division sign into a multiplication sign.
