Answer 1

hi friend ur answer is in the above pic

Answer 2

Answer:

Product of the numbers = 2835

Explanation:

Given ratio of two numbers = 5:7

Let first number = 5x

second number = 7x

LCM of two numbers = 315

[ given ]

=> 5*7*x = 315

=> x = (315)/(5*7)

After cancellation, we get

=> x = 9

Now,

First number = 5x = 5×9 = 45

second number = 7x=7×9=63

product of the numbers = 45×63

= 2835

Therefore,

Product of the two numbers

= 2835
