Cevap

144
First, the two fractional lengths must be combined: 7127 \frac{1}{2} plus 4124 \frac{1}{2} equals exactly 12 feet. Since there are 12 inches in a single foot, the total measurement in inches is found by multiplying the 12 feet by 12. This yields a final answer of 144 inches.

Adım Adım Çözüm

1
Add the lengths of the two pieces of edging together in feet.
712+412=127 \frac{1}{2} + 4 \frac{1}{2} = 12 feet
Finding the total combined length is the first step before converting to the requested unit.
2
Convert the total length from feet to inches.
12×12=14412 \times 12 = 144 inches
There are 12 inches in 1 foot, so multiplying the number of feet by 12 gives the length in inches.

Anahtar Kavram
