how do u add {15'-6 3/4"}+{5'-11 5/8}+{11'-5 7/16}+{6'-9 3/16}?

Answer 1

Convert everything to either fractions or inches. Then add everything in brackets. Next, add the sums in the brackets to each other.

Convert to inches and feet as needed.

Answer 2

Leave the feet alone. Change all the fractions in the inches to sixteenths, so you get 12/16, 10/16, 7/16, and 3/16. Now add these to get 32/16. Reduce that to 2 whole inches. Now add all the inches together to get 6 + 11 + 5 + 9 + the 2 from the fractions, to give you 33 inches. Divide that by 12 to get some of them into feet; you get 2 feet and 9 inches left over. Add the feet up go get 15 + 5 + 11 + 6 + the extra 2; you get 39 feet. So your final answer is 39 feet 9 inches. Step-by-step, it's the only way.

Answer 3

1. get all denominators of the mixed fractions to 16

15 ft 6 3/4 in= 15 ft 6 12/16 in
5 ft 11 5/8 in= 5 ft 11 10/16 in
11 ft 5 7/16 in= 11 ft 5 7/16 in
6 ft 9 3/16 in= 6 ft 9 3/16 in
-------------------------------------------
= 37 ft 31 32/16 in
= 37ft 31 in +32/16= 31 +2 in=33in.

= 37ft 33 in.

12 inches =1ft so 37 ft 33in +24 in=2 feet 39ft 9 in

Answer is 39 feet 9 inches

Answer 4

Loks like a home building project question.

I would change everything to inches first to solve this.
Then Add or subtract the things in parenthesis (()) first, and change the fractions to decimals to make it easier.

Then re-write the problem to have it look like this:

1. {15'-6 3/4"}+{5'-11 5/8}+{11'-5 7/16}+{6'-9 3/16}
2. (180-6.75) + (60-11.625) + (132-5.4375) + (72-9.1875)
3. 173.25+48.375+126.5625+62.8125
4. 411", or 34' 1/4"

Hope that helps.

Answer 5

First scale up all the fractional inch parts so they have 16 as the denominator, then add up the inches and divide by 12; the result is what you add to the feet, and the remainder stays inches
