10)

The sumof two rational numbers is $\frac{7}{6.}$ If one of the number is $\frac{5}{8}$ , find the other.

Answer:_______________

The sumof two rational numbers is $\frac{4}{5.}$ If one of the number is $\frac{8}{7}$ , find the other.

Answer: $\frac{12}{-35}$

SOLUTION 1 :

Given :

Sum of two rational numbers = $\frac{4}{5}$

Given number + Required number = $\frac{4}{5}$

$\frac{8}{7}$ + Required number = $\frac{4}{5}$

Required number = $\frac{4}{5}$ - $\frac{8}{7}$

= $\frac{(28-40)}{35}$

= $\frac{(-12)}{(35)}$

= $\frac{12}{-35}$

The sumof two rational numbers is $\frac{4}{2.}$ If one of the number is $\frac{4}{9}$ , find the other.

Answer: 1 $\frac{4}{9}$

SOLUTION 1 :

Given :

Sum of two rational numbers = $\frac{4}{2}$

Given number + Required number = $\frac{4}{2}$

$\frac{4}{9}$ + Required number = $\frac{4}{2}$

Required number = $\frac{4}{2}$ - $\frac{4}{9}$

= $\frac{(36-8)}{18}$

= $\frac{(28)}{(18)}$

= 1 $\frac{4}{9}$

The sumof two rational numbers is $\frac{6}{5.}$ If one of the number is $\frac{6}{3}$ , find the other.

Answer: $\frac{-4}{5}$

SOLUTION 1 :

Given :

Sum of two rational numbers = $\frac{6}{5}$

Given number + Required number = $\frac{6}{5}$

$\frac{6}{3}$ + Required number = $\frac{6}{5}$

Required number = $\frac{6}{5}$ - $\frac{6}{3}$

= $\frac{(18-30)}{15}$

= $\frac{(-12)}{(15)}$

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

The sumof two rational numbers is $\frac{3}{5.}$ If one of the number is $\frac{2}{8}$ , find the other.

Answer: $\frac{7}{20}$

SOLUTION 1 :

Given :

Sum of two rational numbers = $\frac{3}{5}$

Given number + Required number = $\frac{3}{5}$

$\frac{2}{8}$ + Required number = $\frac{3}{5}$

Required number = $\frac{3}{5}$ - $\frac{2}{8}$

= $\frac{(24-10)}{40}$

= $\frac{(14)}{(40)}$

= $\frac{7}{20}$

The sumof two rational numbers is $\frac{5}{2.}$ If one of the number is $\frac{5}{5}$ , find the other.

Answer: $\frac{3}{2}$

SOLUTION 1 :

Given :

Sum of two rational numbers = $\frac{5}{2}$

Given number + Required number = $\frac{5}{2}$

$\frac{5}{5}$ + Required number = $\frac{5}{2}$

Required number = $\frac{5}{2}$ - $\frac{5}{5}$

= $\frac{(25-10)}{10}$

= $\frac{(15)}{(10)}$

= $\frac{3}{2}$

The sumof two rational numbers is $\frac{6}{2.}$ If one of the number is $\frac{5}{3}$ , find the other.

Answer: $\frac{4}{3}$

SOLUTION 1 :

Given :

Sum of two rational numbers = $\frac{6}{2}$

Given number + Required number = $\frac{6}{2}$

$\frac{5}{3}$ + Required number = $\frac{6}{2}$

Required number = $\frac{6}{2}$ - $\frac{5}{3}$

= $\frac{(18-10)}{6}$

= $\frac{(8)}{(6)}$

= $\frac{4}{3}$

The sumof two rational numbers is $\frac{6}{5.}$ If one of the number is $\frac{3}{10}$ , find the other.

Answer: $\frac{9}{10}$

SOLUTION 1 :

Given :

Sum of two rational numbers = $\frac{6}{5}$

Given number + Required number = $\frac{6}{5}$

$\frac{3}{10}$ + Required number = $\frac{6}{5}$

Required number = $\frac{6}{5}$ - $\frac{3}{10}$

= $\frac{(60-15)}{50}$

= $\frac{(45)}{(50)}$

= $\frac{9}{10}$

The sumof two rational numbers is $\frac{2}{4.}$ If one of the number is $\frac{5}{9}$ , find the other.

Answer: $\frac{1}{-18}$

SOLUTION 1 :

Given :

Sum of two rational numbers = $\frac{2}{4}$

Given number + Required number = $\frac{2}{4}$

$\frac{5}{9}$ + Required number = $\frac{2}{4}$

Required number = $\frac{2}{4}$ - $\frac{5}{9}$

= $\frac{(18-20)}{36}$

= $\frac{(-2)}{(36)}$

= $\frac{1}{-18}$

The sumof two rational numbers is $\frac{7}{4.}$ If one of the number is $\frac{4}{7}$ , find the other.

Answer: $\frac{33}{28}$

SOLUTION 1 :

Given :

Sum of two rational numbers = $\frac{7}{4}$

Given number + Required number = $\frac{7}{4}$

$\frac{4}{7}$ + Required number = $\frac{7}{4}$

Required number = $\frac{7}{4}$ - $\frac{4}{7}$

= $\frac{(49-16)}{28}$

= $\frac{(33)}{(28)}$

= $\frac{33}{28}$

10)

The sumof two rational numbers is $\frac{7}{6.}$ If one of the number is $\frac{5}{8}$ , find the other.

Answer: $\frac{13}{24}$

SOLUTION 1 :

Given :

Sum of two rational numbers = $\frac{7}{6}$

Given number + Required number = $\frac{7}{6}$

$\frac{5}{8}$ + Required number = $\frac{7}{6}$

Required number = $\frac{7}{6}$ - $\frac{5}{8}$

= $\frac{(56-30)}{48}$

= $\frac{(26)}{(48)}$

= $\frac{13}{24}$
