Answer: 250%
==================================================
Step-by-step explanation:
A is 40% of B
This translates to the equation A = 0.40B or A = 0.4B
This is because 40% converts to 0.40 in decimal form
Let's divide both sides by 0.4 to isolate B
A = 0.4B
A/0.4 = B
B = (1/0.4)A
B = 2.5A
This shows that B is 250% of A
------------
Another approach:
40% = 40/100 = 2/5
"A is 40% of B" is the same as "A is 2/5 of B
So,
A = (2/5)*B
5A = 2B
2B = 5A
B = 5A/2
B = (5/2)A
B = 2.5A
which is another way to show that B is 250% of A
