Question

Four - fifth of a number is greater than three - fourths of the number by 4. find the number.

Answer 1

Answer:

number be 'x'

4/5 x - 3/4 x= 4

16x - 15x = 80

x = 80

Answer 2

Answer:

-80/59

Step-by-step explanation:

Solution: Let the number = x, then

4x/5 =(15x/4) + 4

16x = 75x + 80

-59x = 80, or

x = -80/59. Answer.

The answer seems absurd because the question is also absurd.

Check: (4/5)*(-80/59) = -1.084745763

RHS = 4+(15/4)*(-80/59) = -1.084745763
