Answer:
$140
Explanation:
Kate wants to buy a bicycle that normally costs $210. However, there is a sale where she can buy it for two-thirds of the price. So, what we need to is multiply 210 by the fraction 2/3. We can do this is by multiplying 210 by 2 and then dividing it by 3. This will give us the number 140, which is two-thirds of 210, and therefore our answer.
