Answer:
No.
Step-by-step explanation:
2:1 and 19:10 are not equivalent.
Simply, because if you divide 9 by any number with the 10, it is not going to stay as a whole number. For example, 19 divided by 2 equals 9.5. 19 divided by 5 equals 3.8. So, no they are not equivalent.
Answer: No
Explanation: You can't divide 2 into 19 but you can with 1 and 10. If 19 were a 20, it'd be equivalent.
