Chapter 5 - Ratio and Proportion - 5.3 Proportions - 5.3 Exercises: 4

Answer

$\frac{150 trees}{1 acre}=\frac{1500 trees}{10 acres}$

Work Step by Step

We are given that 150 trees is to 1 acre as 1500 trees is to 10 acres. In order to write this as a proportion, we can write both relations as fractions. 150 trees is to 1 acre can be written as $\frac{150 trees}{1 acre}$ 1500 trees is to 10 acres can be written as $\frac{1500 trees}{10 acres}$ Next, we can set both fractions equal to each other, which gives us a proportional relationship. $\frac{150 trees}{1 acre}=\frac{1500 trees}{10 acres}$ Since the units in the numerators and denominators are different, we do not simplify any further.
