$10.50 = 15% of ???

Answer 1

10.5 = 0.15x
divide both sides by 0.15
x = 70

Answer 2

70. It goes like this...10.50 divided by .15 (which is 15%) equals 70. The equation for working with percentages is as follows:
x times 15%=y
y divided by 15%=x

Answer 3

Remember that you can write 15% as a decimal. To write a percentage as a decimal merely move the decimal point to the left two spaces. For example 15.0% = .15 - the decimal point has moved to the left two spaces.

The word "of" is represented mathematically as multiplication, so in your question "15% of ???" means "15% times ???". When typing it is convenient to use "*" to represent multiplication, so "15% * ???"

Finally the "???" in your question is the unknown, it is what we are trying to find, so we can represent it with a variable. To stick with convention we will use "x" fpr "???".

Putting all this knowledge together we can re-write the equation:

$10.50 = 15% of ???
10.50 = 0.15 *x

Now we want to get 'x' by itself. To do this we must look at what operation is occurring to "x" and do the opposite to both sides of the equation. "x" is being multiplied by 0.15, and the opposite of multiplication is division so:

10.50/0.15 = (0.15*x)/0.15 -> notice on the right the two .15s will cancel out:

70.00 = x

And there you have it: $10.50 is 15% of $70.00. I hope this helps, good luck on other problems like this.

Answer 4

15%<---->$10.50
100%<--->(100/15) x $10.50
= 20/3 x $10.50
= 20 x $3.50
= $70
Answer is $70

Answer 5

$10.50*100/15=10.50*20/3=210/3=$70
