PWN the SAT Q&A • I saw the explanation for number 6 on page 594….but to get the answer shouldn’t you do (2/3)xTotal number of eggs=White eggs and see which doesn’t give you a decimal. So if we did 2/3 of 10 (choice A) we get a decimal and this question says EXCEPT so I chose A. B would work because 2/3 of 12 is8

Careful! The ratio you’re given in the problem is 2:3 for white eggs:brown eggs. But the question is asking about the TOTAL eggs (including both white and brown eggs).

This is a classic setup for SAT ratio questions! They’ll tell you about a part:part ratio, and then ask you something about the whole. The MOST IMPORTANT THING YOU CAN DO IN ANY RATIO QUESTION is keep close track of your units and read the question carefully.

Here’s what you should be looking at. Notice that the “total” column is always a multiple of 5, and that white and brown are always in a ratio of 2:3.
