The pair of rational numbers with their sum are matched.
<h3 /><h3>What is rational number?</h3>
The numbers in the form of p/q is called the rational number.
1. -2/a²b +2/ab² = ( -2ab² +2a²b) / a³b³
= 2(a-b)/a²b²
2. 1/2ab -1/4a²b² =( 4a²b² -2ab) / 8a³b³
= 2ab -1 /4a²b²
3. 2/a²b³ -2/ab = (2ab -2a²b³) / a³b⁴
= 2( 1- ab²) /a²b³
4. 1/ab³ -1/a²b = a²b - ab³ / a³b⁴
= (a - b²) / a²b³
Thus, all the rational numbers are matched with their sum.

Answer:
John has 126 apples.
Step-by-step explanation:
If John has 7 full boxes and 7 half boxes and each box has 12 then you have too
12 times 7 = 84 (this id how many apples are in the full boxes)
Then 12 ÷ 2 × 7 = 42 ( the number of half boxes)
Then you add them together:
84 + 42 = 126
So you get 126
