Bill notes that his apple tree is 4/5 the size of his pear tree is apple tree is 4 M tall how tall is the pear tree
e-lub [12.9K]

1) Given that the apple tree is 4/5 pear tree we can write

Apple Tree size = 4/5 Peartree

Apple tree= 4m

2) So we can write the following expression for that:

\begin{gathered} Apple=\frac{4}{5}P \\ 4=\frac{4}{5}_{}P \\ 4P=20m \\ P=\frac{20}{4} \\ P=5 \\  \\  \end{gathered}

So the Pear tree is 5 meters tall, and the apple tree is 4/5*5 = 4 m
