What is 4 3 over 4 plus 10 5 over 12?

Answer 1

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
