Sagot :
100% = 1
75% = 0.75 = 3/4
3/4x = 84 | *4
3x = 336 | /3
x = 112
Or you can do like this:
3/4x = 84 | /3
1/4x = 28
3/4x + 1/4x = 84 + 24
4/4x = 112
x = 112
75% = 0.75 = 3/4
3/4x = 84 | *4
3x = 336 | /3
x = 112
Or you can do like this:
3/4x = 84 | /3
1/4x = 28
3/4x + 1/4x = 84 + 24
4/4x = 112
x = 112
