Answer:
Explanation:
Step 1. Turn it into a problem
14/15-2/7
Step 2. Find the LCM for the bottom and then multiply the top by however many times the bottom goes into the LCM
98/105-30/105
Step 3. Subtract the top numbers but keep the bottom one the same
68/105
Since you can not divide the top and the bottom by the same number, it can not be reduced and therefore the answer is
68/105 of the bottle is remaining
