Question

add
$2 \frac{3}{5}$
to the difference of
$7 \frac{5}{8}$
and
$3 \frac{3}{8}$

​

Answer 1

Answer:

$7 \frac{5}{8} - 3 \frac{3}{8} \\ = \frac{61}{8} - \frac{27}{8} \\ = \frac{61 - 27}{8} \\ = \frac{ \cancel{34}_{ \: \: 17}}{ \cancel{8}_{ \: \: 4} } \\ = \frac{17}{4} \\ \boxed{ = \underline{ \underline{4 \frac{1}{4} }}} \\ \\ 4 \frac{1}{4} + 2 \frac{3}{5} \\ = \frac{17}{4} + \frac{13}{5} \\ = \frac{85 + 52}{20} \\ = \frac{137}{20} \\ \boxed{ = \underline{ \underline{6 \frac{17}{20} }}}$
