Answer: 2 an 1/12
Step-by-step explanation:
You can do this 2 ways
1. 6 and 8/12 - 4 and 7/12
--Start by subtracting the wholes.
-6-4=2
--Next subtract the individual fractions
-8/12-7/12= 1/12
-- All together you would get 2 and 1/12
However most questions might not be this easy (the next way will work every time)
2. 6 and 8/12 - 4 and 7/12
--Start by Making the numbers into improper fractions( that means that the number on top is larger than the one on bottom)
-(do this by multiplying the whole (6 or 4) by the denominator (12) then add that number to the numerator of the fraction)
6*12=72
72/12 + 8/12 = 80/12
6 and 8/12= 80/12
4*12=48
48/12 +7/12 = 55/12
4 and 7/12= 55/12
--Next subtract the new improper fractions
-80/12-55/12= 25/12
-- last convert this improper fraction into a mixed fraction
You do this by seeing how many times the denominator (12) can go into the numerator(25)
12 can go into 25 two times because 12*2=24
This 2 is the whole number
Because 24 is one less than 25 there is 1 left over
This is the numerator of the fraction 2 AND (1/12)
