Answer: 13/20
Step-by-step explanation:
Recall that 60 minutes = 1 hour
So, 39 minutes = Z hour (Let the unknown hour be Z)
Then to get the value of Z,cross multiply
Z x 60 = 39 x 1
60Z = 39
Divide both sides by Z
60Z/60 = 39/60
Z = 39/60
Let 3 divide through 39 and 60
So, Z = 13/20
Thus, 13/20 of an hour is 39 minutes
It is best to make a table for this one
Hour | Cells
0 | 1
1 | 2
2 | 4
3 | 8
4 | 16
5 | 32
6 | 64
7 | 128
After 7 hours, there are 128 cells. To find this, you multiply the starting amount by two each hour.
