The expression evaluates to \( \frac{2434}{9} \).
Solución
We need to evaluate the expression:
15 × 18 + 12 ÷ 3 ÷ 9
Step 1. Handle multiplication and division from left to right.
• First, compute the multiplication:
15 × 18 = 270
• Next, compute the division part:
12 ÷ 3 = 4
Then, 4 ÷ 9 = 4/9
Step 2. Now, add the two results:
270 + 4/9
To combine these, express 270 as a fraction with denominator 9:
270 = 270 × (9/9) = 2430/9
So, the sum becomes:
2430/9 + 4/9 = (2430 + 4)/9 = 2434/9
Thus, the evaluated expression is 2434/9.

To solve the expression \( 15 \times 18 + 12 \div 3 \div 9 \), start by doing the multiplication: \( 15 \times 18 = 270 \). Next, handle the division: \( 12 \div 3 = 4 \) and then \( 4 \div 9 = \frac{4}{9} \). Finally, combine the two results: \( 270 + \frac{4}{9} = 270 \frac{4}{9} \) or \( 270.44 \) when expressed in decimal form. Just remember to follow the order of operations (PEMDAS/BODMAS) to avoid any brain-boggling blunders! Multiplication before addition and always tackle division before combining with other operations.
