1
The lcm of 1.25 and 5 is 125

Answer 2

We have,

Two Numbers 1/1.25 and 1/5

Let us convert 1/1.25 into simpler form.

∴ 1/1.25 = 100/125 (Multiplying both numerator and denominator by 100)

= 4/5 = 0.8

Also,
1/5 = 0.2

LCM of 4/5 and 1/5 = Product of the two numbers/HCF

= 0.16/0.2

= 0.8

Here, you have to find the HCF, and HCF is common mutiples which is only 0.2

Thus L.C.M of 1/1.25 and 1/5 is 0.8
