Question

isaac begins rock climbing at sea level. he rock climbs up 10 feet every minute. how many minutes will it take his to reach an elevation of 70 feet? rewrite the division equation using the multiplicative inverse of 10. 10m = 70 70 ÷ 10 = m 70 · \square = m \frac{1}{10} -\frac{1}{10}

Explanation:

Step1: Find multiplicative inverse of 10

Multiplicative inverse of 10 is $\frac{1}{10}$ (since $10 \cdot \frac{1}{10}=1$).

Step2: Replace division with multiplication

$70 \div 10 = 70 \cdot \frac{1}{10}$, so the blank is $\frac{1}{10}$.

Answer:

$\frac{1}{10}$
