Let's call the number we are looking for x

9 = 4% * x

9 = 4/100 * x

9 = 0.04 * x

x = 9/0.04

x = 225

Nine is 4% of 225.

How to solve this problem
erma4kov [3.2K]
You're going to use cross multiplication.
1 gal x 21 miles = 25miles x x
21 miles = 25x
Divide each side by 25 to get x alone
21/25 = 0.84, which is your x value.

(7 x 10 ^5) + (4 x 10 ^2)
spayn [35]

\huge\text{Hey there!}

\mathsf{(7\times 10^5) + (4 \times 10^2)}\\\mathsf{= 7\times 10^5 + 4 \times 10^2}

\large\textsf{Let's solve for the LEFT SIDE first}

\mathsf{7\times 10^5}\\\\\mathsf{10^5}\\\mathsf{= 10\times10\times10\times10\times10}\\\mathsf{= 100 \times 100\times 10}\\\mathsf{= 10,000 \times 10}\\\mathsf{= 100,000}\\\\\mathsf{7\times100,000}\\\mathsf{= 700,000}

\large\textsf{NEW EQUATION: }\bold{700,000} + {4}\times 10^2

\large\textsf{Now, let's solve for the RIGHT SIDE last}

\mathsf{4\times 10^2}\\\\\mathsf{10^2}\\\mathsf{= 10\times10}\\\mathsf{= 100}\\\\\mathsf{4\times100}\\\mathsf{= 400}

\large\text{NEW EQUATION: 700,000 + \bf 400}

\large\text{700,000 + 400}\\\\\large\text{SIMPLIFY IT!}\\\\\large\text{= 700,400}

\huge\text{Therefore, the answer should be: \boxed{\mathsf{700,400}}}\huge\checkmark

\huge\text{Good luck on your assignment \& enjoy your day!}
