Henry used benchmark fraction to compare the lenghts of grasshoppers 5/8 and 7/4. which grasshopper is longer? explain.

Change the denominators to be the same

5/ 8 = 5/8
7/4 = 14/8

Since the denominators are the same, the larger the numerator, the larger the fraction. Therefore 14/8 (7/4) is greater than 5/8. 

14/8 > 5/8
7/4  >  5/8


The grasshopper that is 7/4 unit long is longer

 The grasshopper that is 7/4 unit long is longer

hope I had helped

The first answer is correct
