Step-by-step explanation:
Direct proportion
60: 1 5 /12 = 120 : x
60: 17/12 = 120:x
Product of extremes = product of mean
60*x = (17/2)*120

It will take 2 5/6 hours to read 120 pages
7th grade: 62/120 of the class is made up of girls; (120-62)/120 of boys.
8th grade: 58/120 of the class is made up of boys; (120-58)/120 of girls.
Looking at the info for boys only: Compare (120-62)/120 with 58/120. What do you see?

Answer:
35 combinations
Step-by-step explanation:
You have to use the formula for finding combinations in probability. It looks like this:
₇C₃ = 
so that gives you
₇C₃ = 
The 4 factorials cancel each other out, and when you do the math, you get 210/6. That divides evenly into 35. So there are 35 combinations.
