Question

Tanner calculates the volume of a rectangular prism with dimensions Three-fourths ft by 5 ft by One-half ft. His work is shown below. V = l w h. V = Three-fourths (StartFraction 5 Over 1 EndFraction) (one-half) = StartFraction 3 (5) (1) Over (4) (1) (2) EndFraction = StartFraction 15 Over 6 EndFraction = 2 and one-half. What error did Tanner make? He multiplied the numerators incorrectly. He multiplied the denominators incorrectly. He simplified StartFraction 15 Over 6 EndFraction incorrectly. He wrote 5 as a fraction incorrectly.

Answer 1

Answer:

He multiplied the denominators incorrectly

Step-by-step explanation:

we know that

The volume of a rectangular prism is given by the formula

$V=LWH$

we have

$L=\frac{3}{4}\ ft\\\\W=\frac{5}{1}\ ft\\\\H=\frac{1}{2}\ ft$

substitute

$V=(\frac{3}{4})(\frac{5}{1})(\frac{1}{2})=\frac{3*5*1}{4*1*2}=\frac{15}{8}\ ft^3$

therefore

He multiplied the denominators incorrectly
