Answer 1

"Seventy percent of what number is 17.5" translates to

0.7x = 17.5

where x is the unknown number

Answer 2

the 0.7 is the decimal form of 70%

Answer 3

if we know that 17.5 is the 100% original number
what is 70% of that? \(\begin{array}{ccllll}
quantity&percentage
\\\hline\\
17.5&100\\
70&x
\end{array}\implies \cfrac{17.5}{70}=\cfrac{100}{x}\)

Answer 4

hmmm I got my quantities swap off =) \(\begin{array}{ccllll}
quantity&percentage
\\\hline\\
17.5&100\\
x&70
\end{array}\implies \cfrac{17.5}{x}=\cfrac{100}{70}j\)

Answer 5

more typos \(\bf \begin{array}{ccllll}
quantity&percentage
\\\hline\\
17.5&100\\
x&70
\end{array}\implies \cfrac{17.5}{x}=\cfrac{100}{70}\)

Answer 6

First you have to change 70% into adecimal:
70=70/100=0.7

Then you basically divide 17.5 by 0.7:

17.5/0.7=?
