Question

Four fifths of a number is subtracted from three fourth of the number by 4.

Answer 1

Step-by-step explanation:

4/5x-3/4=4. LCM 20

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

20

16x-15x =4

20

1x /20=4

x=4*20

x=80

Answer 2

Let the number be x.

Given that 2/5th of a number Subtract from 3/4th of that number gives 14.

(2/5)* × - (3/4)* × =14

x(2/5 - 3/4) = 14

x(8 - 15/20) = 14

-7x/20 = 14

-7x = 14

-7x = 280

x = -280/7

x = -40

Verification

(2/5) * - 40 - (3/4) * - 40 = 14

-16 -(-30) = 14

-16 + 30 = 14

-16 + 30 = 14

14 = 14
