4 divided by 5 eighths​

0.1563       Step-by-step explanation:

Dividing by a fraction is the same thing as multiplying by its reciprocal.  

Step-by-step explanation:

Thus, 4 / (5/8) is the same thing as 4 * (8/5).

Here's why it's so:

4 / (5/8)

Multiply numerator and denominator by 8.

4*8 / (5/8)*8

Clearly, (5/8) * 8 = 5. This gives you:

4*8/5

... which is 4 * (8/5), or 4 times the reciprocal of (5/8).

Naturally, that equals 32/5, or 6 and 2/5.

Hope that helps!
