Question

12 -0.28 ÷ 0.07

Explanation:

Step1: Perform the division

First, calculate the division part: $-0.28 \div 0.07$. We know that $0.28 \div 0.07 = 4$, so $-0.28 \div 0.07 = -4$.

Step2: Subtract from 12

Now, subtract this result from 12: $12 - 4 = 8$ (since we have $12 - (0.28 \div 0.07)$ and we found $0.28 \div 0.07 = 4$, so it's $12 - 4$).

Answer:

8
