2*3:9*5

To solve the expression \( 2 \times 3 : 9 \times 5 \), you first need to clarify how to interpret it. In this context, ":" typically indicates division.

Let's break it down:

1. Calculate \( 2 \times 3 = 6 \)
2. Calculate \( 9 \times 5 = 45 \)
3. Now, divide the results: \( 6 : 45 = \frac{6}{45} \)

Now simplify \( \frac{6}{45} \):

• Divide both the numerator and the denominator by 3.

\[ \frac{6 \div 3}{45 \div 3} = \frac{2}{15} \]

So, \( 2 \times 3 : 9 \times 5 = \frac{2}{15} \).
