Question

Wat percentage should we increase the number 2 to make it 2.5?

Answer 1

Answer:

first we need to find out how much to add

for that, we do 2.5 - 2 = 0.5.

then we find out how much percent of 2 is 0.5

x * 2/100 = 0.5

x/50 = 1/2

by cross multiplying, we get

x = 50/2 = 25.

therefore, we need to add 25% of 2 to 2 to make it 2.5
