John is 1 8 meter shorter than Paul, and Paul is 0.25 meter taller than Andrew. If John’s height is 1 3 4 meters, what is Andrew

9966 [12]

Answer:

Andrew's height is $1\frac{5}{8}$ meters

Explanation:

We know that John's height is $1\frac{3}{4}$ meters

We are given that:

John is $\frac{1}{8}$ meters shorter than Paul

This means that:

Paul's height = John's height + $\frac{1}{8}$

Paul's height = $1\frac{3}{4} + \frac{1}{8} = 1\frac{7}{8}$ meter

We are given that:

Paul is 0.25 meters taller than Andrew

This means that:

Andrew's height = Paul's height - 0.25

Andrew's height = $1\frac{7}{8} - 0.25 = 1\frac{5}{8}$ meters

Hope this helps :)
