How do you convert 8.5 to a fraction explain how you do this please thank you.

Sophie [7]

.5 equals one half.
8 is 8 over one (8/1)
8 + 1/2 = 8 1/2
To make it an improper fraction multiply the denominator (bottom number) by the whole number and add the numerator (top). 8*2=16+1=17
Then, put this number over the existing denominator. 17/2
