The answer to your Q the better one it is the 4- pound bag because it coast less money
First you need to give both fractions a common denominator lets say 40. So N would be 8/40 and Z would be 35/40, so Z collected more than N. All together they collected 43/40 which simplifies to be 1 and 2/40 which would again simplify to 1 and 1/20.
Answer:
X : Z = 6 : 5
Step-by-step explanation:
X : Y = 3 : 1
Double both sides
X : Y = 6 : 2
Y : Z= 2 : 5
Combined
X : Y : Z = 6 : 2 : 5
Therefor
X : Z = 6 : 5
