Question

If you add
$\frac{5}{4}$
to a number and then multiply this resultby
$\frac{11}{5}$
,the result is
$\frac{77}{25}$
.Find out the number.​

Answer 1

Heya!

Let that number be x

ACCORDING TO THE GIVEN QUESTION

( x + 4/5 ) × ( 11/15 ) = (77/25)

( 5x + 4 ) × ( 11 ) = ( 77 × 3 )

( 5x + 4 ) =( 231 /11)

5x = ( 231/11 ) - 4

5x = 187/11

5x = 17

x = 17/5

So, the number which is responsible for all these changes is 17/5
