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

6 and 24

step-by-step explanation:

6 x 4 = 24

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
