How can the fraction 1/2 be used to complete the fractions 3/5 and 4/10? Be sure to include a number sentence using the symbols >, <, or = to compare the fractions 3/5 and 4/10 in your answer.
I know that half of 5 is 2.5, so 3/5 is more than 1/2. I also know that half of 10 is 5, which means 4/10 is less than 1/2. Since one is bigger than a half and the other is smaller, the number sentence is 3/5 > 4/10.
