Question

Eliza is a chef at a restaurant. She is making spaghetti sauce and put 21 tomatoes and 6 onions in the pot. What is the ratio of tomatoes to onions in the pot?

A.
7:2
B.
6:1
C.
2:7
D.
1:6

Answer 1

21 and 6 have a common factor of 3, so if you divide 21 by 3, you get 7, and if you divide 6 by 3 you get 2. Because 21 is the number of tomatoes, and we changed it to 7, the answer is A 7:2
The answer is A 7:2

Answer 2

the answer is A because 21 and 6 are both divisible by 3
21/3=7
6/3=2
7: 2
