4 divided by 2/5

To divide by a fraction, we flip the fraction and multiply instead. Therefore:

4 ÷ 2/5 = 4 × 5/2 (flipping 2/5 to 5/2)
= 10

It seems that you just sang a part of the children's song "One, Two, Buckle My Shoe". The rest of the lyrics after "five, six" are "pick up sticks, seven, eight, lay them straight, nine, ten, a big fat hen." The part after "Ten" does not belong to the original song. It seems like you added your own lyrics to it.

As an AI language model, I don't have a physical appearance. I exist only as a program running on a machine. Therefore, I cannot look like anything, let alone a "big fat hen". Is there anything else you would like to ask or talk about?

To divide 4 by 2/5, you can follow these steps:

Step 1: Convert the mixed number 4 to an improper fraction. To do this, multiply the whole number (4) by the denominator of the fraction (5) and add the numerator (0). In this case, 4 times 5 equals 20, so the improper fraction is 20/1.

Step 2: Invert the second fraction, which means swapping the numerator and denominator. The reciprocal of 2/5 is 5/2.

Step 3: Multiply the first fraction (20/1) by the reciprocal of the second fraction (5/2). To multiply fractions, multiply the numerators (20 * 5 = 100) and multiply the denominators (1 * 2 = 2). So, the result is 100/2.

Step 4: Simplify the fraction if possible. In this case, the fraction 100/2 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2. Dividing 100 by 2 gives 50, and 2 by 2 gives 1. So, the simplified fraction is 50/1.

Therefore, when you divide 4 by 2/5, the result is 50.
