1 foot = 12 inch 72" x 108 " = (72/12 ) feet x (108/12) feet = 6 feet x 9 feet = 54 square feet
0.72 x 150 = 108. So, 108 is 72% of 150.
% Rate = (72/150) x 100% = 48%
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
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
1 foot = 12 inch 72" x 108 " = (72/12 ) feet x (108/12) feet = 6 feet x 9 feet = 54 square feet
0.72 x 150 = 108. So, 108 is 72% of 150.
2/3 x 108 = 72
lcm(72, 108, 216) = 216 Using factorisation: 72 = 2³ x 3² 108 = 2² x 3³ 216 = 2³ x 3³ lcm = 2³ x 3³ = 216
54 = 2 x 2772 = 8 x 9108 = 4 x 27The LCM of 54, 72, and 108 is 8 x 27 = 216.
% Rate = (72/150) x 100% = 48%
2 x 2 x 2 x 3 x 3 = 72 2 x 2 x 3 x 3 x 3 = 108
36 + 36 = 72 72 + 36 = 108 113 - 108 = 5 3 times with 5 remaining 113 - 5 = 108 = 36 x 3

The result of 36 multiplied by anything, is a multiple of 36. For example, 1 X 36=36, 2 X 36=72, 3 X 36=108, so 36, 72, 108 etc... are all multiples.
Let the x represent the nephew's age and 2x represent Ron's age, then state the equation and solve: x + 2x = 108 (next simplify) 3x = 108 (next divide both side by 3 to find the nephew's age) x = 36, hence 2x = 72, and 36 + 72 = 108 Ron is 72 and his nephew is 36.
36, 72, 108 and so on.
