Answer:
Step-by-step explanation:
12x + 24y = 12(x + 2y)
12x - 24y = 12(x - 2y)
12x/24y = 12(x/2y)
Answer:
the proportion is 0.2779, that is a 27.79%
Step-by-step explanation:
The article reported that 1880 children ate fast food from a sample of 6765 children. We can use the rule of three to find the proportion of children that ate fast food
that gives us that a 27.79% of the children ate fast food on a typical day. We can obtain the proportion by dividing the percentage by 100, that gives us a proportion of 27.79/100 = 0.2779.
