Question

use tiles to create an expression that is equal to 11. 11 = 12 + ÷ 3 -

Explanation:

Step1: Simplify division first

We need to fill the first blank with a number that makes $\frac{\text{blank}}{3}$ a whole number. Let's test 9: $\frac{9}{3}=3$

Step2: Calculate the partial expression

$12 + 3 = 15$

Step3: Find the final missing number

We need $15 - \text{blank} = 11$. Rearrange: $\text{blank}=15-11=4$

Answer:

The completed expression is $12 + 9 \div 3 - 4$, with the first blank filled with 9 and the second blank filled with 4.
