To find out how much water Noah needed for 7 plants, each requiring 14 ounces of water, he can calculate it as follows:
The multiplication equation is: \( 7 \times 14 = 98 \) ounces of water.
To check his answer using addition, he can add 14 ounces for each of the 7 plants. The correct addition equation would be:
\( 14 + 14 + 14 + 14 + 14 + 14 + 14 = 98 \)
So, the correct option is: • \( 14 + 14 + 14 + 14 + 14 + 14 + 14 = 98 \).
