whats 2.5% as a fraction or mixed number in simpliest form and as a decimal

Question

hi im having trouble with my math homework please help. thank you

Answer 1

any time you are trying to convert from a percentage to a decimal you can just divide by 100! so this one becomes

2.5% / 100 = 0.025 as a decimal

for fraction then i would write it out of 100 and then simplify as much as possible

2.5/100

= 1 / 40 (if you divide both parts by 2.5)

Answer 2

To convert or express percentages as decimals:  write the percentage (2.5), then divide by 100, which is the same as moving the decimal two places to the left, so 2.5% = 0.025.

If you have a whole number (for example, 25), then same idea:  write the percentage (25) and realize that the decimal is at the right end, just unwritten, so 25 = 25.0

Again, move the decimal left two places (same as divide by 100):  25% = 0.25
