• C. 32/25
• D. 64/125

Answer 1

Answer:

B. 1/8

$(\frac35+\frac15-\frac{3}{10})\times\frac{36}{45}\div\frac{16}{5}$

$=(\frac45-\frac{3}{10})\times\frac{36}{45}\div\frac{16}{5}$

$=\frac{1}{2}\times\frac{36}{45}\div\frac{16}{5}$

$=\frac{18}{45}\div\frac{16}{5}$

$=\frac25\times\frac{5}{16}$

$=\frac18$
