The word 'of' automatically tells us that we have to multiply between the two given values:

3 x 75

5

= 225/5

= 45

Thus 3/5th of 75 is 45.

What we could also have done here is divide 75 into five equal parts (75/5 = 15). In this way we would have found 1/5th of 75. Then 3/5th would have been 15x5=45.

Thus 45 is 3/5th of 75.
