for mary's party, she asked her dad to buy 18 bottles of soft drink. each bottle contained 1 1/4 litres.
the glasses they had for the party hold 1/5 of a litre. how many glasses could be filled from the 18 bottles of soft drink?
18 * 5/4 ÷ 1/5 = 112.5
Well, if each bottle contains 1 1/4 litres of soft drink, we need to convert it into smaller units to figure out how many glasses can be filled. Since each glass holds 1/5 of a litre, let's convert the bottle size to fifths of a litre.
1 1/4 litres equals 5/4 litres.
If we multiply 5/4 by 5 (to get fifths), we get 25/4 fifths of a litre.
So, from one bottle, we can fill 25/4 glasses.
Now, let's calculate how many glasses can be filled from the 18 bottles of soft drink.
18 bottles x 25/4 glasses/bottle = 450/4 glasses.
And, if we simplify it, we can fill 112 and a half glasses.
However, I'm not sure how to pour half a glass, so let's stick with a whole number. Therefore, we can fill a total of 112 glasses from the 18 bottles of soft drink. Cheers!
To find out how many glasses can be filled from the 18 bottles of soft drink, we need to calculate the total amount of soft drink in litres and then divide it by the capacity of each glass.
Each bottle contains 1 1/4 litres, which can be converted to 1.25 litres.
The total amount of soft drink in 18 bottles is 18 * 1.25 = 22.5 litres.
Now, we can divide the total amount by the capacity of each glass, which is 1/5 of a litre.
22.5 litres / (1/5 litre) = 22.5 * 5 = 112.5 glasses.
Therefore, 112.5 glasses could be filled from the 18 bottles of soft drink.
However, since we cannot have half a glass, we have to round down the result to the nearest whole number.
Therefore, the maximum number of glasses that can be filled is 112 glasses.
To find out how many glasses can be filled from the 18 bottles of soft drink, we need to calculate the total volume of soft drink in liters and then convert it to the volume in glasses.
First, let's calculate the total volume of soft drink in liters:
Number of bottles: 18
Volume of each bottle: 1 1/4 liters
To add the fractions, we need to convert the whole number to a fraction:
1 = 4/4
So, 1 1/4 = 5/4
Now, multiply the number of bottles by the volume of each bottle:
18 * 5/4 = 90/4 liters
To convert liters to glasses, we need to find how many glasses are in 1/5 of a liter. Divide the total volume in liters by the volume of each glass:
90/4 liters ÷ 1/5 liter/glass
When we divide fractions, we flip the second fraction and multiply:
90/4 * 5/1 = 450/4 glasses
Now, simplify the fraction:
450/4 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:
450/4 ÷ 2/2 = 225/2
So, Mary's dad can fill 225/2 or 112.5 glasses from the 18 bottles of soft drink. Since we can't have half a glass, we can say that 112 glasses can be filled.
