Answer:

A) option c) about 12

B)  option a) about 9      

Step-by-step explanation:

We have to carry out the following calculation and use compatible numbers to evaluate,

A)

5\times 2\displaystyle\frac{3}{5}\\\\=5\times \frac{13}{5}\\\\=13

Hence, the answer option c) about 12.

B)

25\displaystyle\frac{7}{8}\div 2\frac{8}{9}\\\\=\frac{207}{8}\div \frac{26}{9}\\\\=\frac{207}{8}\times \frac{9}{26}\\\\= 8.95

Hence, the right answer is option a) about 9
