Answer 1

Answer:

49/40 liters

Step-by-step explanation:

Concept= Subtraction

Given= The quantity of total milk and used.

To find= The left over milk

Explanation=

We have been given the question as Michael bought 2 liters of milk. He drank 2/5 liters of it and gave 3/8 liters to his brother. How much milk did Michael have left?

So, the total milk is 2 liters.

Now we are told that Michael drank 2/5 liters of the milk.

So, since he drank the milk the quantity is now reduced.

2 - 2/5

=> LCM of 1 and 5 is 5.

=> (2*5- 2)/5

=> (10-2)/5

=> 8/5 liters

Now after this he gave 3/8 liters to his brother.

The value will be decreased from 8/5 liters because at first he drank and then from reduced quantity he gave it to his brother.

Given to brother = 3/8liters

Let the left over milk be x.

=> 8/5 - 3/8 = x

=> LCM of 5 and 8 is 40.

=> (8*8 - 3*5)/40 =x

=> (64-15)/40 = x

=> 49/40 =x

Therefore the left milk is 49/40 liters.

So, Michael is left with 49/40 liters of milk.
