Gabriellas travel shampoo bottle holds 1 1/2 cups of shampoo. Before leaving on vacation,she filled the bottle to the yop with 1/8 cup cup of shampoo.How much shampoo was already in the bottle?
What do the companies have to do with this question?
I did two of these problems for you. Now it's your turn. I'll be glad to check your answers.
To find the amount of shampoo already in the bottle, we need to subtract the amount Gabriella filled to the top from the total capacity of the bottle.
To solve this, we need to convert the mixed number 1 1/2 into an improper fraction.
1 1/2 can be converted to an improper fraction by multiplying the whole number (1) by the denominator (2) and then adding the numerator (1). This gives us 3/2.
Now, let's subtract the amount Gabriella filled to the top, which is 1/8 cup, from the total capacity of the bottle, which is 3/2 cups.
To subtract fractions, we need a common denominator. The least common multiple of 2 and 8 is 8, so let's convert both fractions to have a denominator of 8.
1/8 is already in terms of 8, but 3/2 needs to be multiplied by 4/4 to get a denominator of 8. This gives us 12/8.
Now, we can subtract the fractions:
12/8 - 1/8 = (12 - 1) / 8 = 11/8
So, there was 11/8 cup of shampoo already in the bottle before Gabriella filled it to the top.
