Step-by-step explanation:
With the problem, it's best to put this into a fraction
8/20 of every student will be absent from school less than five days a year, which can then be simplified to 2/5.
There are multiple ways to go about this problem, but my preferred way is to then take 1/5th of 400, which can be done by taking 1*400/5 which equals 80. Since we are asking for 2/5's, just multiply that number by 2, which gives us 160 students.
Answer:
a. 6 commercials.
b. 12 commercials.
Step-by-step explanation:
a. You know that the entire commercial break is 3.6 minutes.
Then, if each commercial takes 0.6 minutes, you need to divide 3.6 minutes by 0.6 minutes in order to calculate the number of commercials that will be played.
Therefore, you get:
b. The other commercial break has the same lenght that the other one (3.6 minutes), but the commercials are half as long; this means that each commercial takes 0.3 minutes.
Then, you need to divide 3.6 minutes by 0.3 minutes in order to calculate the number of commercials that will be played during this break:
The answer of 10.5 is 32.76 is 312

Step-by-step explanation:
Answer:
80 pieces of wire.
Step-by-step explanation:
It may not come out evenly. If there is a remainder, it won't matter. Just throw it away and go with the integer answer.
Change 3 3/4 to a decimal
3.75
Change the 25 foot roll to inches.
25 feet * 12 inches / foot = 300 inches.
Now how many pieces of wire do we get.
1 piece of wire/3.75 inches = x pieces of wire / 300 inches
3.75 * x = 300
3.75 * x / 3.75 = 300 / 3.75
x = 80
