Question

write 16/20 as a decimal

Answer 1

16/20 equals 0.8
First, find out the whole fraction.
20x5=100
So, 16x5=80.
Now, turn this into a decimal
0.8

Answer 2

16/20 can first be reduced to 8/10, which as a decimal would be 0.8. We can tell because any number divided by ten is the same number with the decimal point moved to the left one time.
Hope that helped =)
