Lonna gave away 13/8 pie to her neighbor. Each pie was cut into 8 pieces. How many pieces of pie did lonna give to her neighbor
tankabanditka [31]

Answer:

13 pieces

Step-by-step explanation:

We are given that each pie was cut into 8 pieces .

therefore 1 pie is equal to 8 pieces

1 pie = 8 pieces

Lonna gave 13/8 pie to her neighbor .

So multiply both sides with 13/8 in the above equation in order to make the right side into 13/8 pie and to find the corresponding number of pieces .

1×\frac{13}{8} pie=8×\frac{13}{8} pieces

\frac{13}{8} pie = 13 pieces
