Question

what is lcm(2/5)+ (1/9)​

Answer 1

LCM (Lowest Common Multiple) is the smallest positive integer that is divisible by both given numbers. We can solve the given fractional values as follows;

• $(\dfrac{2}{5}) + (\dfrac{1}{9})$

Here, firstly we have to find the lowest common multiple of 5 and 9 to given a common denominator to 2 and 1.

So, lowest common multiple of 5 and 9 will be 45. As 45 is divisible by 5 and 9 too. Thus, 45 can share a Common denominator for 5 and 9.

$→\dfrac{18 + 5}{45}$

$→\dfrac{23}{45}$

$→{0.5111...}$
