Find the two natural no in the ratio of 5:7 such that it's lam is 210 with method
let the two numbers be 5x and 7x
"it's lam is 210" , I have no clue what that means.
the LCM is probably 35
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
but how to find you i don t know please try to find practical
To find two natural numbers in the ratio of 5:7, we can follow these steps:
Step 1: Write the given ratio in the form of 5x:7x, where x is a common factor of both numbers.
Step 2: Find the least common multiple (LCM) of the ratio's terms, which is the product of 5 and 7 in this case. LCM(5, 7) = 35.
Step 3: To find the first number, multiply the LCM by the ratio of the first term (5) over the sum of the ratio's terms (5 + 7 = 12). First number = (35 * 5) / 12 = 14.58 (Approximately)
Step 4: To find the second number, multiply the LCM by the ratio of the second term (7) over the sum of the ratio's terms (5 + 7 = 12). Second number = (35 * 7) / 12 = 20.83 (Approximately)
Since we require natural numbers, we need to round these decimal values.
So, the two natural numbers in the ratio of 5:7, whose LCM is 210, are approximately 15 and 21.
