Noah had to water 7 plants. Each plant needed 14 ounces of water. Noah multiplied to find out how much water he would need. Which equation shows the addition equation he could use to check his answer?

Question

14 + 14 + 14 + 14 + 14 + 14 + 14 = 98

14 + 7 = 21

14 + 14 + 14 + 14 + 14 + 14 = 84

7 + 7 + 7 + 7 + 7 + 7 + 7 = 49

Answer 1

To check the answer to the multiplication problem, Noah would want to verify that the total amount of water needed is 98 ounces, which is calculated by multiplying 7 plants by 14 ounces of water each (7 × 14 = 98).

The addition equation that corresponds to adding 14 ounces for each of the 7 plants is:

14 + 14 + 14 + 14 + 14 + 14 + 14 = 98

This shows that he is adding the 14 ounces for each of the 7 plants. Therefore, the correct equation to check his answer is:

14 + 14 + 14 + 14 + 14 + 14 + 14 = 98.
