What is the sum of 20% of 55 plus 22 divided by 40%?
55×20%+22÷40%
=11+55
=66
26% of a number is 150 more than 24%. What's the number?
150÷（26%-24%）
=150÷2%
=7500
(1-40%) x + 55 = 3 / 4x-55, please solve it step by step
The original formula is 60% x + 55 = 3 / 4x - 55
60%x - 3/4x =-110
- 3/20x = - 110
x=2200/3
