4 x 10-5 = 0.00004
40= 10 times 4 10 is breaken down to 2 times 5 bring down the 4 to get 2 times 5 times 4
It is: 4/5 times 10 = 8
4 and 5/5 is the same as 5 so 10*5 = 50
5 goes into 50 10 times.
How many times does 5 go into 20 ?
2/5 times 3/4 = 3/10 in simplest form
3.45 x 10^1
4
10x = 4 x = 4/10= 2/5 = .4
4/5 * 10/13 = 40/65 = 8/13.
