let the two numbers be 5x and 7x
"it's lam is 210" , I have no clue what that means.
Find the two natural no in the ratio of 5:7 such that it's lam is 210 with method
4 answers
the LCM is probably 35
If the larger number is 210, then the ratio says that
5:7 = 150:210
If the larger number is 210, then the ratio says that
5:7 = 150:210
Ans_ 30 & 42
Suppose that to no. Be 5x and 7x as we have to got ratio be 5 :7
One simple method is multiply the ratio (by substituting the value of x, x=1,2,3,4,5,6,7,8,.... ) and then get the lcm of the numbers
If the lcm is 210 then hurraaaaaa....
If not then agian put the value of x and calculate the lcm
Again.
Take x =6
Will give you the no. 30 and 42 respectively... whos ratio is 5:7 and lcm be 210....
Hence, our nos.are 30,42
