Answer:

1 5/12
60 1/16
11/35

Step-by-step explanation:

1) 4 2/3 - 3 1/4 = (4 -3) +(2/3 -1/4) = 1 + (8/12 -3/12) = 1 5/12

2) (7 3/4)/(8/62) = (31/4)(62/8) = (31/4)(31/4) = 961/16 = 60 1/16

3) (2 5/7 +3 2/3) -(4 2/3 +1 2/5) = (2 + 3 -4 -1) +(5/7 +2/3 -2/3 -2/5)

= 5/7 -2/5 = (25 -14)/35 = 11/35

Notes on arithmetic with fractions

It can be helpful to make use of a common denominator when adding or subtracting fractions. Your knowledge of multiplication tables can help you find a suitable common denominator. Without too much effort, you can use the product of denominators as the common denominator, though doing that may require you to reduce the resulting fraction.

If you need a formula for addition or subtraction of fractions, this is it:

a/b + c/d = (ad +bc)/(bd)

A sign can be attached to any of these numbers, so that ...

a/b - c/d = (ad -bc)/(bd)

Using this formula is how we worked problem 3. It is essentially the same as rewriting each fraction to use the common denominator bd:

a/b = ad/(bd)

c/d = bc/(bd)

Of course, division of fractions (or any sort of division, actually) is the same as multiplying by the inverse (reciprocal) of the denominator. The mantra "invert and multiply" can be a useful reminder of this.
