To get the answer we have to multiply 25 times 21 7/8. To do that we have to transform 21 7/8 into improper fraction and thn multiply 25 times numerator.
$21 \frac{7}{8}= \frac{21*8+7}{8}= \frac{175}{8}$
$\frac{175}{8}*25 = \frac{175*25}{8}= \frac{4375}{8}=546 \frac{x}{y} \frac{7}{8}$ - its the answer
