- Simplify:

Let n be the common factor for the ratio 6:5. Then:
6n+5n=330
11n=330
n=30
aerobics=6n=180 min
weight training=5n=150 min

The answer is no
Simplify 8/64= 1/8= 0.125
1/4= 0.25
1. This is one confusing question... But here is what I did
x = 2y + 1
y =

+ 2x
So plug in Y to solve for X
x = 2 (

+ 2x) + 1
x =
- 
Not sure if that's completely correct, but I'm positive I didn't make any mistakes...
5. You have to find the multiples of 60 so...
1 60
2 30
3 20
4 15
