Question

three fourth of a number is greater than three fifth of the number by 12 find the number​

Answer 1

Answer:

x=80

Step-by-step explanation:

Let us assume an unknown number say 'x' .

According to question , three fourth of a number is = 3/4x and

                                        three fifth of a number is = 3/5x

Now the question says 3/4x is greater than 3/5x by 12 ;

3/4x>3/5x by 12

Writing it in the form of equation , we will get

3/4x=3/5x+12

Solving the equation:

(3/4-3/5)x=12

3/20x=12

3x=12*20

x=80

Therefore value of the unknown number which we assumed to be x is =80
