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

We conclude that the sum of two rational numbers is rational.

Hence, the fraction will be a rational number. i.e.

Step-by-step explanation:

Let a, b, c, and d are integers.

Let a/b and c/d are two rational numbers and b≠0, d≠0

Proving that the sum of two rational numbers is rational.

As the least common multiplier of b, d: bd

Adjusting fractions based on the LCM

As b≠0, d≠0, so bd≠0

Therefore, we conclude that the sum of two rational numbers is rational.

Hence, the fraction will be a rational number. i.e.

i think the answer is d im not sure

just get this app called photo math it should be able to do those
