List all the fraction of 84
(5/12) + (3/7) = (35/84) + (36/84) = 71/84
It is: 60/84 = 5/7 in its lowest terms
7/8, 14/16
To subtract fractions with different denominators, you first have to find the equivalent fractions that have equal denominators. In this case, you can multiply top and bottom of 5/12 by 7 to give 35/84. You can multiply top and bottom of 4/7 by 12 to give 48/84. Thus the question can be rewritten as 35/84 - 48/84. This is just a straight subtraction which gives the answer -13/84
The first step is to put the fraction in its simplest form, by dividing both denominator and numerator by any common divisors. In this case, both 21 and 84 can divide by 21, so do this and we get 1/4. The next step to find any equivalent fractions is to multiply top and bottom of this fraction by any integer (1, 2, 3, 4...). This gives the first few equivalent fractions of 21/84 as: 1/4, 2/8, 3/12, 4/16...
Yes, the fractions 15/28 and 45/84 are equivalent, as 45/84 reduces to 15/28.

24/84 = 2/7 in its lowest terms
If you mean 42 then as improper fractions they are 42/1 and 84/2
(5/12) + (3/7) = (35/84) + (36/84) = 71/84
Any with denominators of which their lowest common multiple is 84; for pairs of fractions these are: whole numbers and /84 /2 and /84 /3 and /28 /3 and /42 /3 and /84 /4 and /21 /4 and /42 /4 and /84 /6 and /28 /6 and /84 /7 and /12 /7 and /84 /12 and /14 /12 and /21 /12 and /28 /12 and /42 /12 and /84 /14 and /84 /21 and /28 /21 and /84 /28 and /42 /28 and /84 /42 and /84 /84 and /84 There are further possible fractions when there are three at a time, and so on upwards. With 12 fractions at a time they can all have different denominators, namely: whole numbers, /2, /3, /4, /6, /7, /12, /14, /21, /28, /42 and /84 Though there are other possibilities with one or more repeated denominators. With 13 or more fractions, some of them of necessity will have the same denominator since there are only 12 factors of 84, namely: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 & 84.
