Problem

If A is 80% more than B, by what percent is B less than A?

2

Step

Given A is 80% more than B

A = B + 0.8B
A = 1.8B

3

Formula

Percentage = \$("Difference"/"Orginal") × 100\$

4

Step

The difference between A and B is

A - B = 1.8B - B
A - B = 0.8B

5

Step

Percentage by which B is less than A

\$ A = (A - B) /(A) times 100 = (0.8B)/(1.8B) times 100 \$

\$A = (0.8)/(1.8) times 100\$

\$ A = 0.4444 times 100 = 44.44%\$

6

Solution

So, B is approximately 44.44% less than A.
