Question

15 2/5- 13 1/5+6 3/4

Answer 1

$15 \frac{2}{5} - 13 \frac{1}{5} + 6 \frac{3}{4}$

$15 + \frac{2}{5} - (13 + \frac{1}{5} ) + 6 + \frac{3}{4}$

$15 + \frac{2}{5} - 13 - \frac{1}{5} + 6 + \frac{3}{4}$

$(15 - 13 + 6) + ( \frac{2}{5} - \frac{1}{5} + \frac{3}{4} )$

$8 + \frac{19}{20}$

$8 \frac{19}{20}$

$= 8.95$

Answer 2

Answer:

$\sf{15 + \dfrac{2}{5} - (13 + \dfrac{1}{5} ) + 6 + \dfrac{3}{4}}$

$\sf{15 + \dfrac{2}{5} - 13 - \dfrac{1}{5} + 6 + \dfrac{3}{4}}$

$\sf{(15 - 13 + 6) + \left( \dfrac{2}{5} - \dfrac{1}{5} + \dfrac{3}{4} \right) }$

$\sf{8 + \dfrac{19}{20}}$

$\sf{8 \dfrac{19}{20}}$

= 8.95
