Question

David ate 1/4 of a chocolate pie and peter ate 2/5.What fraction of the pie still remains?

Answer 1

Answer:

Step-by-step explanation:

Pie eaten by David and Peter = (1/4) + (2/5)

                                                  $= \frac{1*5}{4*5}+\frac{2*4}{5*4}\\\\=\frac{5}{20}+\frac{4}{20}\\\\=\frac{9}{20}$

Remaining pie = 11/20
