Cross Post Need Help From Saxon Math Users

My daughter is trying to solve this problem:

Draw a picture to illustrate this fraction story. If 1/3 of the thirty students earned A's on the test, how many students earned A's? What % of students earned A's?

 

We are using the 2nd Ed. Saxon 6/5 and this is Ln 59. According to the ln, she was taught how to do this problem in ln 50. However, they have not shown her how to make a % out of the answer. She did the rest of the problem correctly, and I know the correct answer and even how to get to it. I just don't know how Saxon wants me to get to it. KWIM? She has learned % a little when it comes to shapes, but I don't see any transition to this. HELP.

We have the 1987 version and the question is simply "...how many students earned A's?" It seems that it is an error in that edition to ask about percentage.

My ds is at the same point as your dd! The answer to question 3 is actually a combination of material learned in lesson 50 AND lesson 47. Look at p. 178 for an explaination of finding the percentage of a circle divided into thirds.

 

HTH! :D

Ok, I was wondering, but it seems as if it would not be the same. I am off to look. Thanks.

I have the third edition so the lesson #'s aren't matching up but my dd was doing this over the summer. Finding the percent of 1/3 (doing the division with a remainder) was taught briefly in our lesson #43 but the % amount of thirds, fifths, and eighths were taught more fully in the Investigation #3. Not finding them, but what they are with the manipulatives. I allow dd to keep the manipulatives from that lesson and use them, she ended up memorizing common fractions and their % amounts.
