Question

Identify the part, whole, and percent in the following statement: Find 15% of 750. part = 750, whole = n, percent = 15part = 15, whole = 750. percent=ppart = n, whole = 750, percent = 15none of theseWrite a percent equation that can be used to solve the following problem: 820 is 20% of whatnumber?n=0.2 x 820820 = 0.2 xn0.2 = n < 820none of these

Answer 1

For the first part we have that:

$(750)\cdot(0.15)=112.5$

Now, 112.5 is the part of the percentage, the percent is 15% and the whole is 750.

For the second part, we have that if 820 is 20% of number n, then:

$\begin{gathered} n=\frac{820}{0.2}=4100 \\ \Rightarrow0.2\cdot n=820 \end{gathered}$

Therefore, we can use the equation 0.2xn = 820
