In this tutorial you will be able to follow along step by step on how to solve basic operations involving fractions.

Always in the same order Fractions For addition, use the 3-multiplication method. Reduce answer. + 30 56 86 ÷2 + 43 5 7 You are done! = = = 8 6 24 48 48 ÷2 Give examples 1. 4/5 + ¾;5/8 – 9/2 2; 5/6 x ¾; 10/9 x 6/5; 3. 4/5divided by ¾;7/8 divided by 3/4 Reduce answer Multiply 3 times Always in the same order

For subtraction, use the 3-multiplication method. Reduce. -30 56 -86 ÷2 43 _ 5 - 7 You are done! = = = - 8 6 24 48 48 ÷2 Give examples 1. 4/5 + ¾;5/8 – 9/2 2; 5/6 x ¾; 10/9 x 6/5; 3. 4/5divided by ¾;7/8 divided by 3/4 Reduce answer Multiply 3 times Always in the same order 3

For multiplication, Reduce first For multiplication, Reduce first! then multiply the two numerators and then the two denominators. 5 1 ● 5 ÷3 3 10 ÷2 = You are done! 12 8 ÷2 9 ÷3 4 3 Give examples 1. 4/5 + ¾;5/8 – 9/2 2; 5/6 x ¾; 10/9 x 6/5; 3. 4/5divided by ¾;7/8 divided by 3/4 Reduce first! 4

Solve like multiplication For division, keep the first fraction, change operation to multiplication, flip the last fraction. Now follow the multiplication rules. keep 5 -1 change flip ● 5 _ 3 9 . -3 20 = _ You are done! ÷ = 8 20 8 9 6 2 3 Give examples 1. 4/5 + ¾;5/8 – 9/2 2; 5/6 x ¾; 10/9 x 6/5; 3. 4/5divided by ¾;7/8 divided by 3/4 Follow directions Solve like multiplication 5
