Answer» ANSWER: It is proved below Step-by-step EXPLANATION: (i) HCF of 14 and 21 is=7 LCM of 14 and 21 is 42 Therefore 42 x7=294 which is ALSO equal to 21 x 14= 294 Hence proved (ii) HCF of 27 and 90 is 9 LCM of 27 and 90 = 270 Therefore, 270 x 9=2430 which is also equal to 27 x 90= 2430 Hence, proved Plz mark as the brainliest.

ANSWER: It is proved below

Step-by-step EXPLANATION: (i) HCF of 14 and 21 is=7

LCM of 14 and 21 is 42

Therefore 42 x7=294 which is ALSO equal to 21 x 14= 294

Hence proved

(ii) HCF of 27 and 90 is 9

LCM of 27 and 90 = 270

Therefore, 270 x 9=2430 which is also equal to 27 x 90= 2430

Hence, proved

Plz mark as the brainliest.
