27 is what percent of 54?
13 is 40% of what number?
27/54 =
0.4x = 13
To find the percentage, you can use the formula:
Percentage = (Part / Whole) * 100
1. 27 is what percent of 54?
Let's substitute the values into the formula:
Percentage = (27 / 54) * 100
Calculating the percentage:
Percentage = (0.5) * 100
Percentage = 50%
Therefore, 27 is 50% of 54.
2. 13 is 40% of what number?
Using the same formula:
Percentage = (Part / Whole) * 100
Let's substitute the values into the formula:
40% = (13 / Whole) * 100
Now, to solve for Whole, we need to isolate it. Divide both sides of the equation by 40:
(13 / Whole) = 40% / 100
(13 / Whole) = 0.4
Cross-multiply to solve for Whole:
Whole * 0.4 = 13
Whole = 13 / 0.4
Whole = 32.5
Therefore, 13 is 40% of 32.5.
To find the percentage, we can use the formula:
Percentage = (Part/Whole) * 100
Let's calculate the answers to the given questions:
1. 27 is what percent of 54?
To find the percentage, we need to divide the first number (part) by the second number (whole) and multiply it by 100.
Percentage = (27/54) * 100
Percentage = 0.5 * 100
Percentage = 50%
Therefore, 27 is 50% of 54.
2. 13 is 40% of what number?
Similar to the previous question, we need to determine the whole number. We can rearrange the formula to solve it.
Whole = (Part/Percentage) * 100
Whole = (13/40) * 100
Whole = 0.325 * 100
Whole = 32.5
Therefore, 13 is 40% of 32.5.
