Answer:
21.<u>77</u>
Step-by-step explanation:
The fastest and easiest way to check if two ratios are equivalent is to cross multiply.
1) 15:17
2) 5:7
set it up with the first number of one ratio being multiplied by the second number of the other ratio, e.g.,
a) 15 x 7
b) 5 x 17
the two products you get are 105, and 85, respectively.
Since the two products differ, these ratios are not equivalent
1. A
2. L
3. Q
4. P
5. X
6. H
7. (-4,1)
8.(1,4)
9.(-4,-3)
10.(0,-4)
11. (-2,-1)
12. (5,-4)
You can say that they would have enough for about half a pound alittle more
