Solve the proportion. PLEASE HELP!!

Mathematics
1 answer:
Rufina [12.5K]3 years ago
8 0

The correct answer is A, 2. This is because as you look at the second fraction, 60 is half of 120. Therefore, mimic the second fraction into the first and take half of the denominator from the first fraction. Half of 4 is 2, and therefore the answer is A, 2. It’s essentially cross multiplying by using proportion.

grandymaker [24]

Step-by-step explanation:

The statement in the above question is True.

Sum of three prime numbers (other than  two)  is always odd.

  • 3 + 5 + 5 = 13
  • 5 + 5 + 7 = 17
