Question

The sum of two rational numbers is 17/4. If one of the numbers is 5/2, find the other number.

Answer 1

Bonjour!

Sum of two rational no. = 17/4

One rational no. = 5/2

So, Let the other rational no. be "x".

Therefore,

$= > \frac{5}{2} + x = \frac{17}{4} \\ \\ = > x = \frac{17}{4} - \frac{5}{2} \\ \\ = > x = \frac{17 - 10}{4} \\ \\ = > x = \frac{7}{4}$

So, other rational no. is = 7/4

Hope this helps...:)

Answer 2

your answer
$sum \: = \frac{17}{4} \\ \\ other \: no. = \frac{5}{2} \\ \\ required \: no. = x \\ \\ \\ therefore \\ \\ \\ \frac{5}{2} + x = \frac{17}{4} \\ \\ x = \frac{17}{4} - \frac{5}{2} \\ \\ x = \frac{17 - 10}{4} \\ \\ x = \frac{7}{4}$
