2-3\/25/36

It looks like you're working with a mathematical expression that combines numbers and operations. However, the notation is somewhat unclear.

If you're looking to simplify \( \frac{2 - 3}{25} \div 36 \):

1. Start with the subtraction in the numerator: \[ 2 - 3 = -1 \]

2. Replace in the expression to get: \[ \frac{-1}{25} \div 36 \]

3. Dividing by 36 is the same as multiplying by its reciprocal: \[ \frac{-1}{25} \times \frac{1}{36} = \frac{-1}{900} \]

So, \( \frac{2-3}{25} \div 36 = \frac{-1}{900} \).

If you intended something different, please clarify and I'll be glad to help!
