Question

find the LCM of 2.5, 0.5 and 0.175

Answer 1

Hi,

Here's ur answer :-

If we multiply the given numbers with same value then LCM won't change.

2.5 x 1000 = 2500

0.5 x 1000 = 500

0.175 x 1000 = 175

2500 = 5 x 5 x 5 x 5 x 2 x 2

500 = 5 x 5 x 5 x 2 x 2

175 = 5 x 5 x 7

so, LCM = 5 x 5 x 5 x 5 x 2 x 2 x 7 = 1750


At last divide by 1000.

1750÷ 1000 = 1.75

HOPE IT HELPS (^_^)

Solution :-

L.C.M. of 2.5, 0.5 and 0.175

The L.C.M. of two or more fractions = L.C.M. of numerators/H.C.F. of denominators

First of all remove the decimals and convert these into fractions.

2.5 = 25/10

0.5 = 5/10

0.175 = 175/1000

Now, first we will find the L.C.M. of numerators.

L.C.M. of 25, 5 and 175

25 = 5*5

5 = 5

175 = 5*5*7

= 5*5*7

= 175

L.C.M. of 25, 5 and 175 = 175

Now, we will find out the H.C.F. of denominators.

H.C.F. of 10, 10, 1000

10 = 2*5

10 = 2*5

1000 = 2*2*2*5*5*5

H.C.F. of 10, 10 and 1000 = 2*5 = 10

Thus,

L.C.M. of Numerators/H.C.F. of denominators

= 175/10

= 17.5

Therefore, L.C.M. of 2.5, 0.5 and 0.175 is 17.5
