1. 24 = 4 x 6
2. 45 is 9 times as many as 5
So what I did to solve this is I took a sheet of graph paper and marked 33 squares and I divided 33 by 3 and so there is 21 squares for the 7 side and 12 for the 4 side. Hope this helped :)
The correct way is 3.20 >3.02 because if you wrote it on a number line 3.02 is smaller and closer to 3 and 3.20 is closer to 4 and farther down the number line which makes it greater.
-----3------l----l-------4--
3.02 3.20
1liter=1000milileter
times both sides by 2.07
2.07liter=2070 milileters
Your answer is 2... :)♥♥♥♥♥
