Answer 1

Answer:

$8\frac{2}{5} \: should \:be \: added \:to\: 6\frac{3}{5}\\to\:get \: 15$

Step-by-step explanation:

$Let \: x \: should \:be \: added \:to 6\frac{3}{5}\\to\:get \: 15$

$6\frac{3}{5} + x = 15$

$\implies \frac{33}{5} + x = 15$

$\implies x = 15 - \frac{33}{5}$

$\implies x = \frac{75-33}{5}$

$\implies x = \frac{42}{5}$

$\implies x = 8\frac{2}{5}$

Therefore.,

$8\frac{2}{5} \: should \:be \: added \:to\: 6\frac{3}{5}\\to\:get \: 15$
