Ah yes, one of my favorite topics.
Step 1: Which ever fraction comes first, you will solve it first. For this question, focus on doing 
first. Afterwards, do 
Step 2: First one equals to 1.125. Next, find the LCD (lowest common dominator, which is 10).

Answer:
84 days
Step-by-step explanation:
You would use the LCM to solve this.
12 and 7 don't share any common factors other than 1,
so you would multiply 12 x 7, which gets you 84.
After 84 days they would have raised the same amount.
Answer:
291.05ft²
Step-by-step explanation:
Volume of the aquarium = L³
L is the length of one side of the aquarium
444 = L³
L = cuberoot[444]
L= 7.63ft
Since the glass aquarium is opened at the top
Total surface Area = 5L²
Total surface Area = 5(7.63)²
Total surface Area = 291.05ft²
Hence the minimum exterior surface area of the aquarium is 291.05ft²
