You are just comparing, so you only need to compare the 11/15 to the 13/20.  Get the LCD for fifteenths and twentieths first.

anonymous · Answer

it would be B greater than. since the first numbers (8) are the same you only need to find what the fractions are. is you divide 11 by 15 and 13 by 20 you get the answer

anonymous · Answer

You would do this by getting the LCM for 15 and 20   So, you need to have factors of 3, 5, and 4 in the denominator.

anonymous · Answer

So, your LCD is 3 x 4 x 5 = 60.  For 15:  15 is multiplied by 4 to go to 60, so the numerator gets multiplied by 4 to go to 44.  So, 44/60

For 20, you multiply that by 3 to get to 20, so your numerator is also multiplied by 3 to get to 39.  So, 39/60

And just compare 44/60 to 39/60.

anonymous · Answer

ok so 44/60 is Greater than 39/60 ?
