(20a+108)/15
Step-by-step explanation:
First find LCM of the denominators. U will find it to be 15
Then calculate the number like this.
[(14a)×1/15×1]+[(2a+36)×3/5]
[(14a/15)]+[(6a+108)/15
(14a+6a+108)/15
(20a+108)/15
Answer:
1,080
Why:
First. you have to turn the feet into inches which would make the room 120in. by 144in. and the area of the room would be 17,280 square inches.
Then you have to find the area of the square tiles, and since the sides of the square are the same length , 4x4=16
Last, you have to divide 17,280 by 16 which would give you 1080 tiles

You place the smaller number or single number on the left side of the box then on top of the box for the first square you would take the first number of your two digit number turn that into a whole number then the second number you would put on top of the second box then just multiply them both separately then add them together.
Example number one: first multiply 5x60 you get 300 for the first box then you multiply 5x6 you get 30 so then you would add the 300 and the 30 to get 330. Hope this helps :)
