a) 0.2
b) 0.3
c) 0.4
d) 0.5
correct answer is: a) 0.2
Explanation
The product of two numbers is 0.84.
Ans, their LCM be 4.2.
We know,
Product of two numbers = LCM \times HCF
According to the question.
\rightarrow 0.84=\left(4.2\times HCF\right)
\rightarrow HCF=\large\frac{0.84}{4.2}
\rightarrow HCF=0.2
So that, their HCF is 0.2
Ans: HCF is 0.2.
