For adding fractions, you need to make both denominators the same, then add the numerators. In this case 5/6 and 4/6 have the sum 9/6, which can be simplified to 1 1/2 (fractions are difficult in these answer windows).
5/30 + 4/6 = 1/6 + 4/6 = 5/6
4 + 6 + 6 + 5 + 5 + 4 + 6 + 5 + 5 + 6 + 5 + 5 + 5 + 3 = 70
1/6 + 4/6 = 5/6 (five sixths)
1.75 or 13/4
It's hard to tell what formula you mean from your description, but I think you mean 4 times 3 divided by 4 plus 10 times 5 over 12. Normally multiplication and division is performed before addition so this equals (4 * 3 / 4) + (10 * 5 / 12) 4 times 3 divided by 4 equals 12 divided by 4 equals 3 and on the other side of the plus 10 times 5 divided by 12 equals 50 divided by 12 50 doesn't go exactly into 12 but we can make it equal 25 over 6 to add the results we need to evaluate 3 plus (25 over 6) to do this, we have to use a lowest common denominator, in this case 6 3 plus (25 over 6) equals 3 * 6 over 6 plus (25 over 6) equals (18 over 6) plus (25 over 6) equals (18 + 25) over 6 43 over 6 43 over 6 is a vulgar fraction, so we extract as many whole numbers as possible 43 over 6 equals 42 over 6 plus 1 over 6 equals: 7 plus 1 over 6 7 1/6
5/4 plus 6 = 7 1/4
5/30 + 4/6 = 1/6 + 4/6 = 5/6
It is 4/8 plus 5/6 = 4/3
5/4 plus 6 = 7 1/4
4/5+2/5=6/5
The sum of 5/6 and 4/9 is 1 5/18
(5/6) + (4/6) = 9/6 = 1 and 1/2
4 + 6 + 6 + 5 + 5 + 4 + 6 + 5 + 5 + 6 + 5 + 5 + 5 + 3 = 70
I meant 6 4 over 5 plus 3 3 over 5
4/5 + 6/7 is 1 23/35
(1/6) + (4/6) + (4/8) = (5/6) + (4/8) = (5/6) + (3/6) = 8/6 = 4/3 = 1 and 1/3
1/6 + 4/6 = 5/6 (five sixths)
