Question

Mini ate four-ninths of her apple before lunch and two-fifths of her apple after lunch. what fraction of the apple did she ate in all?

Answer 1

mini first ate 4/9
then she ate 2/5

she ate 4/9+2/5

20+18/45

38/45 apple eaten

Answer 2

$\frac{4}{9}$ + $\frac{2}{5}$

Lowest Common Multiple ( L.C.M) of 5 and 9 is 45

Total fraction of apples eaten= $\frac{20}{45}$ + $\frac{18}{45}$

                                              = $\frac{38}{45}$
