Question

Four-fifths of a number is greater than three-fourths of a number by 8. The number is

Answer 1

Step-by-step explanation:

(4/5)x=x(3/4)+8

(4/5 - 3/4)x=8

(1/20)x=8

x=160

Answer 2

Step-by-step explanation:

$\sf \implies \dfrac{4}{5}x = \dfrac{3}{4} x + 8$

$\sf \implies \dfrac{4}{5}x = \dfrac{3x+32}{4}$

$\sf \implies \dfrac{16}{20}x = \dfrac{15x+160}{20}$

$\sf \implies 16x=15x+160$

$\sf \implies 16x-15x=160$

$\sf x=160$

1. Step 1:- Copy paste the Question.
2. Step 2:- On R.H.S, letting 8 as denominator 4 so it will be 32/4
3. Step 3:- letting the LCM on both sides of the equation same.
4. Step 4:- If, denominator is same on both the sides of the equation, we can simplify rest of the equation without denominator.
5. Step 5:- Solving the equation.

These types of problems can be solved by many ways.
