To divide 12 by the fraction \( \frac{5}{2} \div 5 \), we first need to simplify \( \frac{5}{2} \div 5 \).
-
Recall that dividing by a number is the same as multiplying by its reciprocal. So, we write this as: \[ \frac{5}{2} \div 5 = \frac{5}{2} \times \frac{1}{5} \]
-
Now, multiply the fractions: \[ \frac{5 \times 1}{2 \times 5} = \frac{5}{10} = \frac{1}{2} \]
Now we need to divide 12 by \( \frac{1}{2} \): \[ 12 \div \frac{1}{2} = 12 \times 2 = 24 \]
Thus, the answer to \( 12 \div \left(\frac{5}{2} \div 5\right) \) is \( 24 \).
In fraction form, \( 24 \) can be expressed as: \[ \frac{24}{1} \]
So, the final answer is: \[ \boxed{24} \]
