a standard brick is 2 1/4\ high. what is the total height of 13 standard bricks? assume they are laid dry…

Explanation:

Step1: Convert mixed - number to improper fraction

A standard brick is $2\frac{1}{4}=\frac{2\times4 + 1}{4}=\frac{9}{4}$ inches high.

Step2: Calculate total height

The total height of 13 bricks is $13\times\frac{9}{4}=\frac{13\times9}{4}=\frac{117}{4}$.

Step3: Convert improper fraction to mixed - number

$\frac{117}{4}=29\frac{1}{4}$

Answer:

$29\frac{1}{4}$
