2 and 5. Both 4 and 10 can be divided by 2
4/10 = 2/5
4/10 but if you want to simplify it . . . 2/5
There are only two ways to simplify 10 over 40. These two ways are to write 5 over 20 and 1 over 4. These answers are found by taking common factors of 10 and 40 and dividing them into 10 and 40 to find simpler numbers.
10-4 = 1/104 = 0.0001
Yes, 4/10 simplifies to 2/5
10
2/5 or 40%
104 = 10000
0.4
When you simplify 8 over 10 to its lowest term, the answer is 4 over 5.
10/40 = 1/4 = .25 = 25%
3 and 4/10, which you can simplify, if you so wish.
