How u write 3.7 as mixed number

The whole number is 3, of course, so all we have to do is convert the decimal to a fraction and then simplify.

.7 is 7/10 as a fraction, and since that is its simplest form the answer is:

3 7/10

7 is in the tenths place so you can write it as 7/10.

7/10 cannot be simplified because it has no common factors (7 is prime).

Now add the three in front.

3 7/10
