Answer:
LCM = 315
Step-by-step explanation:
We know the that the product of two numbers is equal to the product of their lcm and hcf.
The ratio of the the numbers is 5:7. Hence, numbers are 5x and 7x.
The HCF of 5x and 7x is x. Therefore, x =9 since, hcf is given as 9.
Hence, the numbers are
5×9 = 45
7×9 = 63
Using the above relation
45×63 = LCM×9
LCM = 315
