Adding Measurements in Feet and Inches
Add 5 feet 2 in + 7 ft 11 in
Solution
Step 1:
1 ft = 12 in
Step 2:
Converting feet into inches and adding
5 ft 2 in + 7 ft 11 in = [5 x 12 + 2] + [7 x 12 + 11] = 62 + 95 = 157 in
Step 3:
Converting inches into feet
157 in = $\frac{157}{12}$ ft = 13 ft 1 in
Step 4:
So, 5 feet 2 in + 7 ft 11 in = 13 ft 1 in
Add 8 feet 5 in + 12 ft 9 in
Solution
Step 1:
1 ft = 12 in
Step 2:
Converting feet into inches and adding
8 ft 5 in + 12 ft 9 in = [8 x 12 + 5] + [12 x 12 + 9] = 101 + 153 = 254 in
Step 3:
Converting inches into feet
254 in = $\frac{254}{12}$ ft = 21 ft 2 in
Step 4:
So, 8 feet 5 in + 12 ft 9 in = 21 ft 2 in
