Firstly it is easiest if you convert them into full fractions (with no whole numbers on the side so the fraction is top heavy)4 x 12 = 487 + 48 = 56So 4 and 7 twelves is equal to 56 twelvesSimilarly we can work out 3 and 11 twelves3 x 12 = 3611 + 36 = 47So this is equal to 47 twelvesBecause the denominator is the same, you can simply subtract the nominator:So you have 56 twelves subtract 47 twelves56 - 47 = 9. so the answer is 9 twelvles.This can then be simplified by dividing by three to get,The answer is 3/4 (three quarters).
3 times 12 = 36
9/12= 3/4
No. 3/4 = 9/12
4/12 = 1/3
If you mean 8 and 7/12 subtract 2 and 3/8 then it is 6 and 5/24
36
three fourths
3 eights = 24 5 twelves = 60 Their sum is 24 + 60 = 84
Sixteen twelves OR one and two twelves 16/12 = 14/12 = 11/3
If you mean twelfths then it is 8 because 8/12 = 2/3
3/4
