Question

Last week Connor and his roommates ate 1 1/6 cartons of yogurt, and this week they ate 3 cartons. How much more yogurt did they eat this week compared to last week?

Answer 1

1 5/6 3= 2 6/6 and then subtract 1 1/6 and get 1 5/6

Answer 2

Step-by-step explanation:

last week they ate 1 1/6 = 6/6 + 1/7 = 7/6 cartons.

this week they ate 3 = 3×6/6 = 18/6 cartons.

so, how much more did they eat ?

it is not fully clear to me, if we need to find the absolute difference in cartons, or if we need the factor between both amounts (like "how many times did they eat more ?").

to be safe I give you both.

in absolute difference :

18/6 - 7/6 = 11/6 cartons = 1 5/6 cartons more.

as factor :

7/6 × x = 18/6

7x = 18

x = 18/7

they ate 18/7 = 2 4/7 times more
