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.
(2 x 9) + (5 x 9)
= 7 x 9
= 63
$63 is the answer.
Hope it helped! :-D

30-30+7f=30-30
7f=0
Divde by 7
7f/7=0/7
Cross out 7 and 7, divide by 7. Becomes 1*1*f=f
f=0
Answer: f=0
