Question

Simplify - 3 6/7 - 4 + 3 1/5

Answer 1

Answer:

$-\frac{163}{35}$

Step-by-step explanation:

$-3 \frac{ 6 }{ 7 } -4+3 \frac{ 1 }{ 5 }$

$-\frac{21+6}{7}-4+\frac{3\times 5+1}{5}$

$-\frac{27}{7}-4+\frac{3\times 5+1}{5}$

$-\frac{27}{7}-\frac{28}{7}+\frac{3\times 5+1}{5}$

$\frac{-27-28}{7}+\frac{3\times 5+1}{5}$

$-\frac{55}{7}+\frac{3\times 5+1}{5}$

$-\frac{55}{7}+\frac{15+1}{5}$

$-\frac{55}{7}+\frac{16}{5}$

$-\frac{275}{35}+\frac{112}{35}$

$\frac{-275+112}{35}$

$-\frac{163}{35}$
