Question

answer this please..................​

Answer 1

Answer:

75/7

Step-by-step explanation:

1st number = -7/15

Let the other number be ' x '

Prodict of both = -5

=> - 7/15 * x = -5

=> -7x = -5

15

=> - 7x = -5 * 15

=> - 7x = - 75

=> x = -75/(-7)

=> x = 75/7

Answer 2

➤ Answer :-

${\tt \longrightarrow \dfrac{( - 7)}{15} \times \sf(x) \tt = - 5}$

To find the value of 'x' in the following sum, we should divide the answer and the first value given...............

$\sf \longrightarrow (x) \tt = (- 5) \div \dfrac{( - 7)}{15}$

${\tt \longrightarrow \dfrac{( - 5)}{1} \div \dfrac{( - 7)}{15}}$

While dividing two fractions, first we should take the reciprocal of second fraction and multiply both the fractions................

${\tt \longrightarrow \dfrac{( - 5)}{1} \times \dfrac{15}{( - 7)} = \dfrac{( - 5) \times 15}{1 \times ( - 7)}}$

${\tt \longrightarrow \dfrac{( - 75)}{( - 7)} = \boxed{\tt 10 \dfrac{5}{7}}}$

$\Huge\therefore$The other number is ${\tt 10 \dfrac{5}{7}}$
