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)
[tex]5\times 2\displaystyle\frac{3}{5}\\\\=5\times \frac{13}{5}\\\\=13[/tex]
Hence, the answer option c) about 12.
B)
[tex]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[/tex]
Hence, the right answer is option a) about 9
