How many 1 1/2 liter bottles of water does it take to fill a 16 liter jug
timurjin [86]

11 bottles are needed to fill a 16 liter jug

<em><u>Solution:</u></em>

Given that, there is a 16 liter jug

There are 1\frac{1}{2} liters of bottle

<em><u>Let us first convert the mixed fraction to improper fraction</u></em>

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator.

\rightarrow 1\frac{1}{2} = \frac{2 \times 1 + 1}{2} = \frac{3}{2} = 1.5

Thus the bottle is of 1.5 liter

We have to find the number of 1.5 liter bottles needed to fill 16 liter jug

Divide 16 by 1.5 to get result

Number\ Of\ Bottles = \frac{16}{1.5} = 10.67 \approx11

Thus 11 bottles are needed to fill a 16 liter jug
