Now we have: .8 is what percent of 15 = 5.33
Question: .8 is what percent of 15?
Percentage solution with steps:
Step 1: We make the assumption that 15 is 100% since it is our output value.
Step 2: We next represent the value we seek with {x}.
Step 3: From step 1, it follows that {100\%}={15}.
Step 4: In the same vein, {x\%}={.8}.
Step 5: This gives us a pair of simple equations:
{100\%}={15}(1).
{x\%}={.8}(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
\frac{100\%}{x\%}=\frac{15}{.8}
Step 7: Taking the inverse (or reciprocal) of both sides yields
\frac{x\%}{100\%}=\frac{.8}{15}
\Rightarrow{x} = {5.33\%}
Therefore, {.8} is {5.33\%} of {15}.

- - simply multiply the number by 100%
Examples
- 1/4 = 0.25 = 0.25 × 100% = (0.25 × 100)% = 25%;
- 7/8 = 0.875 = 0.875 × 100% = (0.875 × 100)% = 87.5%
- 1.3/9.4 ≈ 0.138297 = 0.138297 × 100% = (0.138297 × 100)% = 13.8297%
- 4.3 = 4.3 × 100% = (4.3 × 100)% = 430%;
