16b) part to part
how do i get the answer to question 16 part b
16b) The problem states that there are 13 boys and 14 girls. This means that there are 27 total students. Since the question asked for the ratio of girls to boys, this is a part to a part (part of the class to part of the class).
If the question asked for a ratio of girls to the total, then this would be part to the whole (total students in class).
how do I do number 16 part b
i love UCLA
USC all the way! Fight On!
see above for 16b
i don't get number 12
to do number twelve divide.
12) Since Edwin drove 140 miles at 50 miles per hour, the unit rate is 40 miles per hour.
I'm stuck on number 17 can you help me?
17) 21% of 66
you can either change the percent to a decimal or fraction
0.21 * 66
21/100 * 66

Mr. Berchtold was driving home! :)
can you help me then?
i cant do that one either
I can't get the correct answer on 15(b 1.85 divided by 6
you have to find the unit rate and you round to the nearest hundredth
Yes, Katie is correct. You need to carefully organize your information.
price/number of apples
$3.60/12 (don't forget, a dozen is 12)
$0.30 per apple
price/number of apples
0.3083 or about $0.31 per apple
Store A is cheaper with a unit rate of $0.30 per apple and store B has a unit rate of about $0.31 per apple
I am having trouble with number 17. I know the answer but I don't know how to get it.
Mr.Berchtold I don't get question number 4 ???
4) In the class,there are 20 students (total) and 13 are boys. Write out what you know:
girls: 7 (if 13 out of 20 are boys, that leaves 7 girls 20 - 13)
Now the question says to find what percent of the students (total) are girls.
7/20 = ?/100 (percents are out of 100)
multiply both the numerator and denominator by 5 and you get 35/100 or 35%
How do I get number 1.
1) Write in words first
%/100 = is/of
25/100 = 12/? you cant go from 25 to 12, so you need to simplify the first fraction by 25.
1/4 = 12/?
Multiply both the numerator and denominator by 12 and you get 48
I will be going to school tommorw and I need help on 17
