It is 3 over 7.
No.
132/240 = 11/20
42/132 = 7/22
9/132 = 3/44
Yes.
It is: 48/132 = 4/11 simplified
83/132 cannot be simplified as hcf(83, 132) = 1.
132/240 can be simplified to 11/20
Yes, 3 over 22 (3/22) because 18 and 132 both can be divide by 6.
Oh honey, let's simplify this mess. 62 over 132 reduces down to 31 over 66 when you divide both numbers by 2. So, there you have it, simplified just like that.
72/132 factor out 12 12*6/12*11 now, as 12 is a shared factor it can be canceled, top and bottom 6/11 --------simplified
