Question

Стакан вмещает 200г молока. какую часть стакана нужно наполнить, что бы в нём оказалось 160 г молока? Какая часть стакана останется незаполненой?

Answer 1

160/200=4/5=0,8
1-0,8=0,2

Answer 2

Calculating Milk in a Glass

To calculate the portion of the glass needed to hold 160g of milk, we can use the following formula:

Portion of the glass needed = (Amount of milk) / (Total capacity of the glass)

Using the given information: - Amount of milk = 160g - Total capacity of the glass = 200g

We can calculate the portion of the glass needed to hold 160g of milk:

Portion of the glass needed = 160g / 200g = 0.8

So, 0.8 or 80% of the glass needs to be filled to hold 160g of milk.

Remaining Unfilled Portion

To find the remaining unfilled portion of the glass, we can subtract the portion needed to hold 160g of milk from 1 (or 100%).

Remaining unfilled portion = 1 - 0.8 = 0.2

So, the remaining unfilled portion of the glass is 0.2 or 20%.
