Answer 3

Comparing Fractions in 5th Grade Mathematics

1) Comparing 14/19 and 18/19: - To compare these fractions, we can find a common denominator and then compare the numerators. - The common denominator for 14/19 and 18/19 is 19. - Since the denominators are the same, we can directly compare the numerators. - 14 is less than 18, so 14/19 is less than 18/19.

2) Comparing 7/15 and 7/13: - Again, we need to find a common denominator to compare these fractions. - The common denominator for 7/15 and 7/13 is 195. - After finding the common denominator, we can compare the numerators. - 7/15 is equivalent to 91/195, and 7/13 is equivalent to 105/195. - Therefore, 7/15 is less than 7/13.

3) Comparing 1 and 3/5: - To compare a whole number with a fraction, we can convert the whole number to a fraction with the same denominator as the fraction. - 1 is equivalent to 5/5. - Now we can compare 5/5 and 3/5, and we find that 5/5 is greater than 3/5.

4) Comparing 26/21 and 1: - To compare a fraction with a whole number, we can convert the whole number to a fraction with the same denominator as the fraction. - 1 is equivalent to 21/21. - Now we can compare 26/21 and 21/21, and we find that 26/21 is greater than 21/21 (which is 1).
