Answer:
72 and 90
Step-by-step explanation:
Hello. Look at all multiples of nine between 61 and 107. They are 63,72,81,90,99 (all multiples of nine are also divisible by 3)
Now divide each of these numbers by 3 and see which give even numbers as answers. Only 72 and 90 give even quotients when divided by 3.
Hence only 72 and 90 are multiples of 3 , 6 and 9 between 61 and 107
