To solve the expression \( 21:96 + 753 \), we first need to clarify what "21:96" means. If we interpret "21:96" as a ratio, it can be simplified.

Assuming it means \( \frac{21}{96} \):

1. Simplifying \( \frac{21}{96} \):

   • Both 21 and 96 can be divided by 3.
   • \( \frac{21 \div 3}{96 \div 3} = \frac{7}{32} \).

2. Now, convert \( \frac{7}{32} \) into a decimal to add it to 753:

   • \( \frac{7}{32} \approx 0.21875 \).

3. Now add 0.21875 to 753:

   • \( 753 + 0.21875 = 753.21875 \).

Therefore, if "21:96" refers to the fraction \( \frac{21}{96} \), the final result is:

753.21875.
