Question

By what no. Should -12/35 be divided to get 3/7 ?

Answer 1

Answer:

Let the missing number be 'x'

$\frac{-12}{35}$  ÷  x  = $\frac{3}{7}$

$\frac{-12}{35}$   ×   $\frac{1}{x}$  = $\frac{3}{7}$

$\frac{-12}{35x}$  =.  $\frac{3}{7}$

35x  ×  3 = - 12 × 7

105x = -84

x = $\frac{-84}{105}$

x = $\frac{-4}{5}$

∴ The missing number is $\frac{-4}{5}$
