Expert Answer
Converting 0.64 and 7.2 into like decimals, we get
0.64 and 7.20
Now, expressing these numbers without decimals as the product of primes,
64 = 2 x 2 x 2 x 2 x 2 x 2 = 26
720 = 2 x 2 x 2 x 2 x 3 x 3 x 5 = 24 x 32 x 5
Now, LCM of 64 and 720 = 26 x 32 x 5 = 2880
Thus, LCM of 0.64 and 7.2 = 28.80 (taking 2 decimal places)
