Answer:
Explanation:
Answer = 3/4 yards
But you want the long answer right? No?
So you have 3 lengths 5/6, 1/4, 2/3. You need to add them, but uh oh! You don't have a common denominator. So we have to find it, use it to change up the fractions, then add them.
so common denominator of 6, 4, and 3 is 12
Change up the fractions appearance for addition:
5/6 = 10/12 (multiply 6 and 2 to get 12, so we multiply5 and 2 to get 10)
1/4 = 3/12 (multiply 4 and 3 to get 12, so we multiply 1 and 3 to get 10)
2/3 = 8/12 (multiply 3 and 4 to get 12, so we multiply 2 and 4 to get 8)
Now add em up!
10/12 + 3/12 + 8/12 = 21/12 yards in total.
Now what? He uses one yard of cable, so you subtract said one yard from the total you have: 21/12
21/12 - 1 (like this chief)
Equivalent fractions are needed here again, so let's convert 1 to a fraction we can work with!
1 = 1/1 (Because 1/1 equals 1)
1/1 = 12/12 (multiply 1 and 12 to get 12 in the denominator, so multiply 1 and 12 in the denominator to get 12)
Okay! Now let's subtract!
21/12-12/12 = 9/12 yards
Reduce fractions: 3/4 yards
You got this!
