Step 1:
Find simpler numbers to solve the problem.
630 feet is about 600 feet.
2 1/2 feet is about 3 feet.
Step 2:
Solve the problem with the simpler numbers.
I will divide, so 600 / 3 = 200 steps.
Step 3:
Change the mixed number divisor to a fraction. Then multiply the dividen by the reciprocal of the divisor:
[tex]\begin{gathered} 630\div2\text{ }\frac{1}{2}=? \\ 630\div\frac{5}{2}=? \\ 630*\frac{2}{5}=252 \end{gathered}[/tex]
Sally takes 252 steps to get from one base of the arch to the other.
