Respuesta :
the 1st holds 3/5
the 2nd holds 1 1/4
the 3rd holds : 1 1/4 - 1/2 = 5/4 - 1/2 = 5/4 - 2/4 = 3/4
how much more does the 3rd hold then the 1st...
3/4 - 3/5 = 15/20 - 12/20 = 3/20 <== it holds 3/20 more
the 2nd holds 1 1/4
the 3rd holds : 1 1/4 - 1/2 = 5/4 - 1/2 = 5/4 - 2/4 = 3/4
how much more does the 3rd hold then the 1st...
3/4 - 3/5 = 15/20 - 12/20 = 3/20 <== it holds 3/20 more
