Answer for the second question:
5*2 is 10
10 *2 is 20
20*2 is 40
40*2 is 80
80 *2 is 160
That's five hours
160*2 is 320
320*2 is 640
640*2 is 1280
1280*2 is 2560
The answer should be 2560
I forgot how to do it with the equation sorry
LCM of 10 & 4 = 20
8/10 * 2 & 5/4*5
16/20 & 25/20
THE 2 RATIONAL NUMBERS BETWEEN 16/20 & 25/20 ARE
17/20,18/20 ect
Step by step, we have:
1 • （-1）= -1
Then -1 • 1 = -1 and -1 • （-1）= 1 =》 1 - 1 = 0
The answers is 0
