Given, 4/7 of the birthday cake was eaten on your birthday
Fraction of cake left = 1 – 4/7 = 3/7
Now, next day your dad ate 1/2 of what was left
$({\rm{Fraction\;of\;cake\;left}} = \frac{3}{7} - \frac{1}{2} \times \frac{3}{7} = \frac{3}{{14}})$
Fraction of cake left = 1 – 4/7 = 3/7
Now, next day your dad ate 1/2 of what was left
$({\rm{Fraction\;of\;cake\;left}} = \frac{3}{7} - \frac{1}{2} \times \frac{3}{7} = \frac{3}{{14}})$
