(−17):(−1)= ? (-17):(-1)=\text{ ?} (−17):(−1)= ?
Note that we are dividing two negative numbers, therefore the result must be a positive number.
Let's rewrite the exercise as a simple fraction:
171= \frac{17}{1}= 117=
Remember the rule:
x1=x \frac{x}{1}=x 1x=x
Any number we divide by 1 will be equal to itself, therefore:
171=17 \frac{17}{1}=17 117=17
+17 +17 +17
