Answer:
#1 = Yes
#2 = Yes
#3 = No
Step-by-step explanation:
Question #1
1:4 , 2:8 , 3:12, 5:20
We can think of proportions as fractions
1/4 , 2/8 , 3/12 , 5/20
These fractions can all be simplified to 1/4, so the answer is yes.
Question #2
2:3 , 4:6, 6:9, 10:15
Once again, we can think of proportions as fractions
2/3 , 4/6, 6/9, 10/15
These fractions can also be simplified, to 2/3 this time. So this answer is also yes.
Question #3
Now we need to compare Chris's use of cranberry juice to Jenny's
As we can tell, 1/4 (Chris's) does not equal 2/3 (Jenny's), so the answer is no.
Hope this helps :)
