Question

by what number should minus 15 by 66 be divided to get minus 5 upon 7

Answer 1

Heya !!

Let -15/66 should be divided by X to get -5/7.

Therefore,

-15/66 ÷ X = -5/7

-15 / 66 × 1/X = -5/7

66X × 5 = -15 × 7

66X = ( -15 × 7 /5 )

66X = -21

X = -21/66 = -7/22

Hence,

-15/66 should be divided by -7/22 to get -5/7.

Hola Mate!!

Your answer :-

$let \: the \: number \: = x \\ \\ ↪ \frac{ - 15}{66} \div x = \frac{ - 5}{7} \\ \\ ↪ \frac{ - 15}{66} \times \frac{1}{x} = \frac{ - 5}{7} \\ \\ ↪ \frac{1}{x} = \frac{ - 5}{7} \times \frac{ - 66}{15} \\ \\ ↪ \frac{1}{ x} = \frac{22}{7} \\ \\ ↪ x = \frac{7}{22}$
