US Edition 6A Ex. 22 # 1 & 2

5 posts in this topic

Hi all, 

I have a question for US Ed. 6 A p. 58 Ex. 22 #1 & 2. The questions for both number 1 and 2 are "How many percent more boys than girls are there?"

The answer in the Home Instructor Guide pg. 128: percent more boys than girls= (difference/ #girls) x 100%.

Why is it not (difference/total # girls and boys) x 100%?

Please help me to understand the question/solution.

Thank you

The question is how many percent more than girls. The word girls comes after the than, that is what it is being compared to, so is the base.

The second equation you have is what is "How many more boys than girls are there as a percentage of the total number of boys and girls"

The question is: How many more boys than girls as a percentage of the total number of girls"

Is this Dimensions Math or Primary Math? Primary Math does not have try it's.  Make a new post under Dimensions Math 1, rather than replying to another post.
