Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

Multiply the numerators (numbers on top):

1 × 3 × 6 = 18

Multiply the denominators (numbers on the bottom):

10 × 5 × 5 = 250

Write the result as a fraction:

18/250

Simplify the fraction by dividing both numbers by their greatest common divisor (GCD), which is 2:

18 ÷ 2 = 9

250 ÷ 2 = 125

So, the simplified result is:

9/125
