<u><em>Answers:</em></u>
a. liters/glass
b. 0.4 liters/glass
c. 400 ml/glass
<u><em>Explanation:</em></u>
<u>Part a:</u>
We are given that two bottles each holding 2 liters of soda
This means that the total amount of soda = 2 * 2 = 4 liters
To get the amount of soda in each glass, we will simply divide the amount of soda by the number of glasses (given the number of glasses is 10)
<u>Therefore:</u>
Amount of soda in each glass = liters/glass
<u>Part b:</u>
We are now asked to express the amount in fraction. The simplest way to do this is to make the denominator a multiple of 10. The number of zeroes in the denominator will be equal to the number of digits after the decimal point
<u>Therefore:</u>
liters/glass
<u>Part c:</u>
Now, we know that 1 liter is equivalent to 1000 ml
<u>Therefore:</u>
0.4 liters = 0.4 × 1000 = 400 ml/glass
Hope this helps :)
