They can both be simplified to the same fraction, 1/3, so yes, they are equivalent.
No, 30 over 90 = 1 over 3, 1 over 10 cannot be simplified any further
There are 26/30 and 13/15 (examples)
15/24, 60/96, 90/144 etc. (divide or multiply both top and bottom by the same number to get an equivalent fraction)
8/15 − 1/6 = 33/90 or 11/30
90/150, 900/1500 are two equivalent fractions.
24/30 = 12/15 = 48/60 = 72/90, etc...
No.
No, 30 over 90 = 1 over 3, 1 over 10 cannot be simplified any further
Some equivalent fractions of 2/15 are: 4/30 = 6/45 = 8/60 = 10/75 = 12/90
Some equivalent fractions of 4/15 are: 4/15 = 8/30 = 12/45 = 16/60 = 20/75 = 24/90
