Question

The sum of two rational number is 73/63. If one rational number is 5/7,find the other rational number

Answer 1

73/63 - 5/7 = 73-45/63 = 28/63 = 4/9

Answer 2

$\underline{ \frak{\large{ \: \: Given : \: \: }}}$

• The sum of two rational number = $\frac{73}{63}$
• One of them =$\frac{5}{7}$

$\underline{ \frak{\large{ \: \: To Find : \: \: }}}$

• The another number

$\underline{ \frak{\large{ \: \:Solution : \: \: }}} \\ \\ \bigstar \: \text{Let the another number be x }$

According to the question : –

$\longrightarrow \: \frac{5}{7} + \text{x} = \frac{73}{63} \\ \\ \longrightarrow \: \text{x} = \frac{73}{63} - \frac{5}{7} \\ \\ \longrightarrow \: \text{x} = \frac{73 - 45}{63} \\ \\ \longrightarrow \: \text{x} = \frac{28}{63} \\ \\ \longrightarrow \: \textbf{x} = \frac{4}{9} \\ \\ \underline{ \fbox{\bf{So, \: the \: other \: rational \: number \: is \: \: \frac{4}{9} }}}$
