are the statement true or false?
1.3:5 and 12:20 are equal ratios.
2.If the cross products are equal,ratios are equal.
3.⅘=¹⁶/18
4.if x/15= 12/36, then x=3.
5.⅗=⁶/10 so 3×6=5×10.
6. 7 miles in 10 minutes=3.5 miles in 5 minutes.
7.6 is to P85 is better than 8 is to P100.
8.12/24 =56/112
9.80:2=600:15
10.proportions is the equality of two ratios.
no nonsense
