What is the least to greatest in 3/4,3/10,2/5, 7/10? break it down for me so i can explain it to a 9 yr. old

3/10, 2/5, 7/10, 3/4

Step-by-step explanation:

3/10 is 30%. 2/5 is 40%. 7/10 is 70%. 3/4 is 75%. Or you could multiply the denominators so that all denominators have the value of 20. Then it can be arranged. For 3/4, you can multiply everything by 5 to get 15/20. for 3/10, you can multiply everything by 2 to get 6/20. For 2/5, you can multiply everything by 4 to get 8/20. And for 7/10, you can multiply everything by 2 to get 14/20. Now you can arrange everything, starting with 3/10, then 2/5, then 7/10, and finally 3/4.
