Prove the sum of two rational numbers is rational where a, b, c, and d are integers and b and d cannot be zero.

steps reasons
1. a over b plus c over d given
2. ad over bd plus cb over bd
3. ad plus cb all over bd simplify

fill in the missing reason in the proof.
multiply to get a common denominator.
add to get a common denominator.
distribute d to all terms.
add d to all terms

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
