Question

The HCF and LCM of two numbers m and n are 6 & 210 respectively. if m+n=72 then 1/m+1/n is equal to​

Answer 1

Answer:

Product of the HCF and LCM of two numbers is the same as the product of the numbers themselves. I.e. if m & n are two numbers, mn = LCM x HCF

mn = 6x210 = 1260

m + n = 72 (given)

Now, 1/m + 1/n = (m+n)/mn = 72/1260 = 2/35

Answer 2

Answer:

Step-by-step explanation:

Product of the HCF and LCM of two numbers is the same as the product of the numbers themselves. I.e. if m & n are two numbers, mn = LCM x HCF

mn = 6x210 = 1260

m + n = 72 (given)

Now, 1/m + 1/n = (m+n)/mn = 72/1260 = 2/35
