Question

N+3/4=19/20. What is N = to?

Answer 1

(19/20)-(3/4)= 1/5, n= 1/5

Answer 2

Thanks! so then what would N- 1/5= 7/20 be?

Answer 3

(7/20)+(1/5)= 11/20

Answer 4

Wait I still dont get how that ='s 11/20 cuz, 7+1=8... and 20 and 20= 20

Answer 5

when u add fractions, u cant really add across until u find a common denominator. so (7/20)+(1/5), to get a common denominator, u can just multiply 5*4 to get 20, then u would have to multiply 4 with the number at the top, which is 1. so u get (7/20)+(4/20), u have a common denominator now, so u can just add across, 7+4=11, and u dont ever really add denominators together bc they are the same

Answer 6

Thanks so much!!

Answer 7

np :) hope my explanation helps

Answer 8
