Answer:
C.
Step-by-step explanation:
So there are 20 kids with brown hair and this represents 80% of the class total.
So this means 20=.8n since we don't know the total number of kids.
20=.8n
Divide both sides by .8
25=n
So 25 is the total number of kids.
C. is the answer
You could also setup this equation given that 80% is 80/100:
[tex]\frac{20}{\text{ total }}=\frac{80}{100}
To figure out what that total is there you can divide top and bottom of the fraction on right hand side by 4 which gives you the 20 on top and the 25 on bottom.
True. There are more options available as to someone who doesn’t get their high school diploma.
4 + 2 + 7 = 13
7/12 + 3/4 + 5/12 = 7/12 + 9/12 + 5/12 = 21/12 = 1 9/12 = 1 3/4
13 + 1 3/4 =
14 3/4 <===
