Answer 1

Step-by-step explanation:

45 is the correct option

Answer 2

Answer:

HCF=9

Product of two numbers=210

Let one number be x then, other number will be (2×9)=18

Now,

\begin{gathered}x \times 18 = 210 \\ = > x = \frac{210}{18} \\ = > x = 11.6666\end{gathered}

x×18=210

=>x=

18

210

=>x=11.6666

The second number is 11.6666 .

other no. is 18
