63 grams of protein in 9 ounces of tuna.

Step-by-step explanation:

Equivalent ratios are a rule of three problem.

In this problem, we have that:

3 ounce serving of tuna provides 21 grams of protein. To find the equivalent ratio, how many grams of protein are there in one ounce serving of tuna?

3 ounces - 21 grams

1 ounce - x grams

The ratio is 7 grams of protein per ounce, so 7:1.

So in 9 ounces of tuna, there are 9*7 = 63 grams of protein.
