Question

The sum of two rational numbers is 5 upon 18 If one of the numbers is 1 upon 8 find the other.
step by step​

Answer 1

Answer:

$\mathtt\pink{SOLUTION:-}$

$\mathtt{ \frac{1}{8} + x = \frac{5}{18} }$

$\mathtt{ \frac{1 + 8x}{8} = \frac{5}{18} }$

$\mathtt{ 1 + 8x = \frac{5}{18} \times 8 }$

$\mathtt{1 + 8x = \frac{20}{9} }$

$\mathtt{8x = \frac{20}{9} - 1}$

$\mathtt{8x = \frac{20 - 9}{9} }$

$\mathtt{8x = \frac{11}{9} }$

$\mathtt{x = \frac{11}{9} \div 8}$

$\mathtt{x = \frac{11}{9} \times \frac{1}{8} }$

$\mathtt{x = \frac{11}{72} }$

$\mathtt\pink{OTHER \: RATIONAL \: NUMBER \: IS \: \frac{11}{72} }$
