(−0.3):(−1)= ? (-0.3):(-1)=\text{ ?} (−0.3):(−1)= ?
Note that we are dividing two negative numbers, so the result must be a positive number.
Let's rewrite the exercise in the form of a simple fraction:
0.31= \frac{0.3}{1}= 10.3=
Remember the rule:
x1=x \frac{x}{1}=x 1x=x
Any number we divide by 1 will be equal to itself, therefore:
0.31=0.3 \frac{0.3}{1}=0.3 10.3=0.3
+0.3 +0.3 +0.3
