To divide 18 2/5 by 4, we need to convert the mixed number (18 2/5) into an improper fraction.

To do this, we multiply the whole number (18) by the denominator (5) and add the numerator (2). Then we place the result over the denominator.

18 * 5 = 90 90 + 2 = 92

So, 18 2/5 is equivalent to the improper fraction 92/5.

Now, we can divide 92/5 by 4. When dividing fractions, we multiply the numerator of the first fraction by the reciprocal of the second fraction.

92/5 ÷ 4 = 92/5 * 1/4

To multiply fractions, we simply multiply the numerators together and the denominators together.

(92 * 1) / (5 * 4) = 92/20

The fraction 92/20 can be simplified by finding the greatest common divisor (GCD) of the numerator and denominator, which is 4 in this case.

92 ÷ 4 = 23 20 ÷ 4 = 5
