Question

How many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water?

Answer 1

The number of 1/5 liter glasses that Lin can fill is
`7(1)/(2)`

Explanation:

we know that

To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5

so

`1(1)/(2) :(1)/(5)`

Convert mixed number to an improper fraction

`1(1)/(2)=1+(1)/(2)=1(1*2+1)/(2)=(3)/(2)`

substitute

`(3)/(2) :(1)/(5)`

Multiply in cross

`(5*3)/(2*1)=(15)/(2)=7.5`

Convert to mixed number

`7.5=7+(1)/(2)=7(1)/(2)`
