Question

The product of two numbers in 7/8. If one of the number is 8/5
find the other number.​

Answer 1

Step-by-step explanation:

Let the required rational number be = x

Other number = (-7/15)

Product of rational number = (-5)

⇒ (-7/15) × x = (-5)

⇒ -7x = (-5) × 15

⇒ X = (-75/-7) = 75/7

∴ The required rational number = 75/7

Answer 2

Solution:-

Given:-

Product of two numbers is $\frac{7}{8}$

One number is $\frac{8}{5}$

To find:-

The other number.

Formula:-

Product = 1st number × 2nd number

By the Problem:-

$Product = 1st \: number * 2nd \: number \\ \frac{7}{8} = \frac{8}{5} * 2nd \: number \\ 2nd \: number \: = \frac{7}{8} \times \frac{5}{8} \\ 2nd \: number = \frac{35}{64}$

Answer:-

The other number is $\frac{35}{64}$

Verification:-

$Product=1st \:number * 2nd \:number\\ Product= \frac{8}{5} *\frac{35}{64} \\ Product=\frac{7}{8} (Hence Proved)$
