1. 1/6 yd, 2/3 yd, 5/6 yd
2. 1/2 foot, 2/3 foot, 5/6 foot
3. 2/15 of an hour, 1/3, 3/4
4. 4/13 of a year, 8/13, 12/13
5. 1/2 of a pound, 5/8, 7/8
6. 1/4 of a year, 1/3, 5/6
7. 1/4 of the salary
8. 6/25 of the book
Step-by-step explanation:
Every week, the radioactivity decreases by a factor of 5
After 1 week, it goes from 5,000 to 1,000
2 weeks 1,000 / 5 =200
3 weeks 200 / 5 = 40
4 weeks 40 / 5 = 8
5 weeks 8 / 5 = 1.6
6 weeks 1.6 / 5 = 0.064
7 weeks 0.064 / 5 = 0.0128
8 weeks .0128 / 5 = 0.00256
9 weeks 0.00256 / 5 = 0.000512
10 weeks 0.000512 / 5 = 0.0001024
I would say if you at least try to make it then you will end up making it
