Question

For a designer suit, Daniel must specify his waist size in centimeters. If there are $12$ inches in a foot and $30.5$ centimeters in a foot, then what size should Daniel specify, in centimeters, if his waist size in inches is $34$ inches? (You may use a calculator on this problem; answer to the nearest tenth.)

Answer 1

Given:

1 foot = 12 inches

1 foot = 30.5 cm

Find 34 inches in feet:

$12 \text{ inches } = 1 \text{ foot}$

$1 \text{ inch } = 1 \div 12 \text{ foot}$

$1 \text{ inch } = \dfrac{1}{12} \text{ foot}$

$1 \text{ inch } = \dfrac{1}{12} \text{ foot}$

$34 \text{ inches } = \dfrac{1}{12} \times 34$

$34 \text{ inches } = \dfrac{17}{6} \text{ feet}$

Find 34 inches in cm:

$1\text { foot} = 30.5 \text{ cm}$

$\dfrac{17}{6} \text { foot} = 30.5 \times \dfrac{17}{6}$

$\dfrac{17}{6} \text { foot} = 86.4 \text{ cm}$

Answer: 86.4 cm
