what is the formula for finding % of a #?

example:

1. find 40 % of 160?

2. 24 is 100 % of what?

also,

how do you do this problem?

4/6 of 48

1.

0.4 * 160

2.
This one should be obvious.

3.
(4/6) * (48/1) = 192/6 = 32

Thank you very much Mrs. Sue! What about the formula for 54 is 10 % of what?

You're welcome.

0.1x = 54

you are an amazing help and are very much appreciated!

Glad we can help. :-)

To find the percentage of a number, you can use the formula:

Percentage = (Number × Percentage) / 100

Now let's apply this formula to your examples:

1. To find 40% of 160, you can use the formula:
(160 × 40) / 100 = 64
So, 40% of 160 is 64.

2. To find 100% of a number when you already have the percentage, you can use the formula:
(Number × 100) / Percentage
In this case, we want to find 100% of some number, given that it is 24. We'll set up the equation:
(24 × 100) / 100 = 24
So, 24 is 100% of itself.

Now, let's address your last question:

To find 4/6 of 48, you need to multiply 48 by the fraction 4/6. The process would be as follows:

Multiply numerator (4) by the number (48) and divide it by the denominator (6):

(4 × 48) / 6 = 192 / 6 = 32
So, 4/6 of 48 is 32.
