Question

solve for r.
7r = 637
r =
submit

Explanation:

Step1: Divide both sides by 7

To solve for \( r \) in the equation \( 7r = 637 \), we divide both sides of the equation by 7. This is because we want to isolate \( r \), and since \( r \) is multiplied by 7, dividing by 7 will undo that operation. So we have:
\[
\frac{7r}{7}=\frac{637}{7}
\]

Step2: Simplify both sides

Simplifying the left side, \( \frac{7r}{7} \) simplifies to \( r \). For the right side, we calculate \( \frac{637}{7} \). Let's do the division: 7 times 91 is 637 (because \( 7\times90 = 630 \) and \( 7\times1=7 \), so \( 630 + 7=637 \)). So we get:
\[
r = 91
\]

Answer:

\( 91 \)
