Reduce the following ratio to its lowest terms and to an equivalent ratio having the smallest term 1 : 30:60:36

To reduce the ratio to its lowest terms, we divide all the terms by their greatest common divisor (GCD).

The GCD of 1, 30, 60, and 36 is 6.

Dividing all the terms by 6, we get the reduced ratio:

1 : 30 : 60 : 36

Simplifying further, we have:

1 : 5 : 10 : 6
