Question

There is 4/8 of a pizza. What unit fraction can be used to describe the fraction of pizza that is left. Give a solution and a explanation.

Answer 1

4/8 can still be simplified into 1/2.

There is still 1/2 of the pizza left.

4 ÷ 4 = 1
8 ÷ 4 = 2

4/8 of a pizza is 1/2 of a pizza.

4/8 = 0.50
1/2 = 0.50 They are still equal.

We can also use proportion: a/b = c/d where ad = bc
4/8 = 1/2
4*2 = 8*1
8 = 8
