Question

ramu drank 3by4th a bottle of milk and her sister drank 4by5th a bottle of milk (the bottles are of the same size) who drank more and by how much?​

Answer 1

Answer:

Ramu's sister drank more by 1

Step-by-step explanation:

We can find it by cross multiply or by taking L.C.M.

First of all we will find it by cross multiply

We will do 3/4×4/5

That will be 3×5= 15

And 4×4 = 16

By doing this we find that here 4/5 > 3/4

So Ramu's sister drank more by =

16-15 = 1

Now we will find the solution by taking L.C.M.

By taking L.C.M. we will find the denominator to be 20 .

And numerator 15 of Ramu and 16 of Ramu's sister

Here , 16>15

So you can see that 16 is bigger and this is of Ramu's sister

Hence , Ramu's sister drank more by =

16-15 = 1
