How many square feet in 72'' x 108''?
1 foot = 12 inch 72" x 108 " = (72/12 ) feet x (108/12) feet = 6 feet x 9 feet = 54 square feet
What number is 72 percent of 150?
0.72 x 150 = 108. So, 108 is 72% of 150.
What percent is 72 out of 150?
% Rate = (72/150) x 100% = 48%
How do you find that the LCM of 72 and 108 is 216?
To find the Least Common Multiple, you factor both values, then multiply the highest exponent of each factor. (You are removing common factors to find a multiple that is smaller than just multiplying the two numbers together.)Example: for 72 and 108, the obvious multiple is 72 x 108 = 7776, but we can find a smaller one.72 = 2 x 2 x 2 x 3 x 3 --- (23 x 32)108 = 2 x 2 x 3 x 3 x 3 --- (22 x 33)The highest exponent of each factor is 23 and 33, and 8 x 27 = 216You can see that 216 is (72 x 3) or (108 x 2). There is no smaller even multiple.--------Rather than using the exponential formula, you can also multiply the common factors by the uncommon factors.Common factors = 2 x 2 x 3 x 3 (36)Uncommon factors = 2 and 3 (6) and 36 x 6 = 216
What can you multiply and get 216?
These: 1 x 216, 2 x 108, 3 x 72, 4 x 54, 6 x 36, 8 x 27, 9 x 24, 12 x 18, 18 x 12, 24 x 9, 27 x 8, 36 x 6, 54 x 4, 72 x 3, 108 x 2, 216 x 1
