Question

I request for someone to give me the step by step working out of these two questions. Thanks a lot, you're a lifesaver;)

Answer 1

Answer:

2)810/18

Step-by-step explanation:

2)HCF x LCM =No. A x B

Therefore, HCF x LCM / A = B

Therefore B= 90 x 9 / 18

= 810/18

Pleeeeease thank the answer and mark me the brainliest

Answer 2

Answer:

(i)non terminating decimal.

(ii)45.

Step-by-step explanation:

(i)its an non terminating decimal81104177208073l

2.811041772080733........

(ii)If a , b are two numbers and their

LCM = L and HCF = H then

a × b = L × H

*********************************************

Now ,

Let a = 18 ,

b = ?

L = 90 ,

H = 9 ;

18 × b = 90 × 9

b = ( 90 × 9 )/18

b = 45

Therefore ,

Required second number = b = 45
