Fifteen is __% of 120.

It is 12.5%.

15 divided by 120 is 0.125, and in order to make it a percentage, multiply by 100% or move the decimal two places to the right.

Another way is to think about it and break it down. 60 is 50% of 120, and 15 is 25% of 60.
Since 15 is 25% of 60, which in turn in 50% of 120, 15 is 12.5%.

I'm 1,000% sure it's correct.

To do this, divide 15 by 120. You get 0.125 Then turn the decimal into a percent. You do this by moving the decimal point to places to the RIGHT. You get 12.5% as your answer.

How do you solve this problem? (x+3) cubed

Lubov Fominskaja [6]

You would expand becausee it isn't equal to anything

(x+3)^3=(x+3)(x+3)(x+3)
we can use binomial theorem or pascal's triangle
anyway, pascal's triangle is more practicl for this one

so
for the 3rd power
$(a+b)^3=1a^3+3a^2b^1+3a^1b^2+1b^3$

a=x
b=3

$(x+3)^3=1x^3+3x^2(3^1)+3x^1(3)^2+1(3)^3$ =
$x^3+9x^2+27x+27$
