Work Step by Step

We can write the given ratio as a fraction and then simplify in lowest terms. Since 1 hours has 60 minutes, we can write 5 hours as $(5\times60)=300$ minutes. $\frac{300 minutes}{100minutes}$ Since both the denominator and numerator have the same unit, we can divide out the common unit. $\frac{300}{100}=\frac{300\div100}{100\div100}=\frac{3}{1}=3$
