1.	Find The Lcm Of Following Three Fractions:36/,48/,72/?
Answer» Numerators = 36, 48 and 72. 72 is largest number AMONG them. 72 is not divisible by 36 or 48 START with table of 72. 72 x 2 = 144 = divisible by 72, 36 and 48 ? LCM of numerators = 144 Denominators = 225, 150 and 65 We can see that they can be DIVIDED by 5. On dividing by 5 we get 45, 30 and 13 We cannot divide further. So, HCF = GCD = 5 LCM of fraction =144/5. Numerators = 36, 48 and 72. 72 is largest number among them. 72 is not divisible by 36 or 48 Start with table of 72. 72 x 2 = 144 = divisible by 72, 36 and 48 ? LCM of numerators = 144 Denominators = 225, 150 and 65 We can see that they can be divided by 5. On dividing by 5 we get 45, 30 and 13 We cannot divide further. So, HCF = GCD = 5 LCM of fraction =144/5.

Answer»

Numerators = 36, 48 and 72.

72 is largest number AMONG them. 72 is not divisible by 36 or 48

START with table of 72.

72 x 2 = 144 = divisible by 72, 36 and 48

? LCM of numerators = 144

Denominators = 225, 150 and 65

We can see that they can be DIVIDED by 5.

On dividing by 5 we get 45, 30 and 13

We cannot divide further.

So, HCF = GCD = 5

LCM of fraction =144/5.

Numerators = 36, 48 and 72.

72 is largest number among them. 72 is not divisible by 36 or 48

Start with table of 72.

72 x 2 = 144 = divisible by 72, 36 and 48
