Answer:
top left is 3/10
top right is 5/10 or 1/2
bottom left is 5/100
bottom right 25/100 or 1/4
Explanation:
So to do it, you need to see what place behind the decimal the number is. The one in the top left is in the tens place, so it is 3 over 10. The one on the top right could also be written as 1/2 because both 5 and 10 can be divided by 5 so you divide top and bottom by 5 and it is simplified. The ones that are in the hundreds place, have a hundred in the denominator. If there was a question with three numbers behind the decimal point it would have 1000 in the denominator because it is in the thousands place.
