It takes 10 pounds of potatoes to make 15 pounds of mashed potatoes at this rate: How many pounds of potatoes are needed to make 50 pounds of mashed potatoes?

75

Step-by-step explanation:

its 15 times 5 (i think this is wrong it seems too easy)

make a ratio which is 50 over 15 equals 10 over x. then you have 50x over 50 because you have to cross multiply equals 150 over 50 then you get the answer three

Step-by-step explanation:

you had to make a ration and cross multiply

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
