Question

find the lcm of 2.5,0.5and 0.175.

Answer 1

LCM of 2.5, 0.5 and 0.175 is 0.5

Answer 2

$2.5 = \frac{2500}{1000} \\0 .5 = \frac{500}{1000} \\ 0.175 = \frac{175}{1000} \\ 2500 = 2 \times 2 \times 5 \times 5 \times 5 \times 5 \\ 500 = 2 \times 2 \times 5 \times 5 \times 5 \\ 175 = 5 \times5 \times 7 \\ LCM(2500 \: 500 \: 175) = {5}^{4} \times {2}^{2} \times 7 = 17500 \\ lcm = \frac{17500}{1000} \\ = 17.5 \: \: \: ans$
