Answer:
64.75 inches
Explanation:
Let's set "x" to be Aiden's brother's height.
Let's form an expression then solve for x.
Given that he is 37 inches tall, we'll set the whole expression to equal 37.
Also given that he is 4/7 as tall his brother, "as tall" meaning multiplication. And, since he is as tall as his brother's unknown height, we'll multiply 4/7 and x together since "x" represents his brother's height and 4/7 is the height we are using to determine how tall he is.
Let's make it:
4/7 · x = 37
Solve!
4/7x = 37
Divide both sides by 4/7, so we're essentially multiplying both sides by 7/4.
*7/4 *7/4
x = 64.75
His brother is 64.75 inches tall.
