0.61 has 2 decimal places, so we put the decimal digits of 0.61, 61 over 1 followed by the number of zeroes equal to the number of decimal places, 

2:     61/1 = 61/100.

0.61 as  decimal fraction  = 61/100

2.8 with a bar over 8 means that it is 2.8 repeated. since we want to find which rational number is equal to 2.8 repeat, let’s calculate them.a) 22/9=2.4 repeatb) 24/9=2.6 repeatc) 26/9=2.8 repeatd) 28/9=3.1 repeatsince 2.8 repeat is the answer we’re looking for, the answer is c.
