Question

how to solve the question 4+7/8

Answer 1

Remember : You cannot add numerator until you make the denominator same.
$4 + \frac{7}{8}$
Therefore, we have to make the denominator same as 8 by multiplying 8 in numerator and denominator both.
$\frac{4 \times 8}{8} + \frac{7}{8}$
$\frac{32}{8} + \frac{7}{8}$
$\frac{32 + 7}{8}$
$\frac{39}{8}$

Answer 2

$4 + \frac{7}{8}$
$\frac{4}{1} + \frac{7}{8}$
$\frac{32 + 7}{8}$
$\frac{39}{8}$
$4.875$
