Step-by-step explanation:

1-4/7

(7-4)/7

3/7*1/2

=3/14

Answer 2

Answer:  The cake left is   $\dfrac{3}{14}$

Step-by-step explanation:

As the total fraction is 1 therefore

Let the whole cake be 1

Now $\dfrac{4}{7}$ was eaten on birthday

therefore cake left

$1-\dfrac{4}{7} = \dfrac{3}{7}$

Now $\dfrac{1}{2}$ of the remaining is eaten

Therefore cake eaten

$\dfrac{1}{2} \times \dfrac{3}{7} = \dfrac{3}{14}$

Cake left

$\dfrac{3}{7} - \dfrac{3}{14} = \dfrac{3}{14}$

Hence , the cake left is   $\dfrac{3}{14}$
