1. A breakfast cereal is made of oats, nuts, and raisins. The advertisements boast that 25% of the cereal in each box is almonds

kotykmax [81]

Answer:

Step-by-step explanation:

1) The advertisements boast that 25% of the cereal in each box is almonds. It means that the percentage of the other cereals in the box is 100 - 25= 75%

Therefore, the portion of each box that is not almonds is 75/100 = 0.75

2) The advertisements boast that 25% of the cereal in each box is almonds. If each box contains 12 cups of cereal, then the number of cups of almonds in each box is

25/100 × 12 = 3 cups

3) if each box contains 12 cups of cereal, and 4 cups are oats, then the percentage of each box that is oats is

4/12 × 100 = 33.33%

What is 1 1/4 × 4 3/4 =

Luden [163]

First, we need to turn this into an improper fraction. Therefore we have: 1 1/4 = 5/4 and 4 3/4 = 19/4
Now we multiply across and eliminate as needed.
5/4 * 19/4 = 95/16
Finally, we reduce and convert to a mixed fraction.
16 goes into 95, 5 times with a remainder of 15. Therefore, we can conclude that our answer is: 5 15/16.
