Answer:
32
Step-by-step explanation:
Biscuits at the start : 72
Number of biscuits given to his grandmother : 2/9 of 72
> 2/9 × 72
> 16
16 biscuits were given to his grandmother
Number of biscuits left now : 72 - 16
= 56
Number of biscuits given to his cousin : 3/7 of 56
> 3/7 × 56
> 24
Number of biscuits Abraham has now : 56 - 24
= 32
