Answer:
21 tables
Explanation:
First, let’s simplify the ratio by dividing both sides by 11.
Once we’ve done that, we're left with a ratio of 3 tables for every 7 chairs.
Because 49 is divisible by 7, we will divide seven and get a quotient of 7.
All that’s left is to multiply 7 by 3, and get our final answer of 21 tables sold.
