Answer 1

Answer:

hey mate your answer is here..........

sum of two rotational number is 4/5

one of them is 2/15

Answer 2

$\huge\mathfrak\blue{Answer:}$

Rational Number:

• Rational Number are the numbers that can be written in the form of a/b where a and B are integers and b is not equal to zero
• For ex : 2/3 , 3/5 , 5/7 etc

Given:

• We have have given that sum of two rational numbers is 4/5
• One of the number is 2/15

To Find:

• We have to find the of other number

Solution:

First number = 2/15

Let the second number be = x

$\underline{\large\mathfrak\red{According \: to \: the \: Question:}}$

$\implies \boxed{\sf{Sum \: of \: Numbers = \dfrac{4}{5} }}$

$\implies \sf{x + \dfrac{2}{15} = \dfrac{4}{5} }$

Shifting all constant to Right Hand side

$\implies \sf{x = \dfrac{4}{5} - \dfrac{2}{15}}$

Taking LCM on RHS

$\implies \sf{x = \dfrac{4 \times 3 - 2}{15} }$

$\implies \sf{x = \dfrac{12 - 2}{15} }$

$\implies \sf{x = \dfrac{10}{15} }$

$\implies \boxed{\sf{x = \dfrac{2}{3} } }$

Hence Second number is 2/3
