(i) 12.15 and 21​

Answer 1

Step-by-step explanation:

sorry I don't know how to find LCM of decimal numbers please give thanks for this phone

Answer 2

WE KNOW THAT HCF * LCM = PRODUCT OF THE TWO NUMBERS.

THEREFORE HCF * LCM = 12.15 * 21 = 255.15

WE CAN WRITE 12.15 AS 1215/100

AND 21 AND FIND HCF AND LCM SEPERATELY!

(OR)

MULTIPLY BOTH OF THEM BY 100 AND THEN FIND HCF AND LCM SEPERATELY
