julia has 8 red barrettes. 2/4 of her barrettes are red. how many barrettes does julia have?
please explain, is it one whole?
16
To answer this question, we need to find out the total number of barrettes Julia has based on the given information.
We know that 2/4 of Julia's barrettes are red. This means that 2 out of 4 barrettes are red.
We can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2 in this case.
2 divided by 2 is 1, and 4 divided by 2 is 2.
So, this fraction simplifies to 1/2, which means 1 out of 2 barrettes are red.
We also know that Julia has 8 red barrettes.
Since 1/2 of Julia's barrettes are red, we can set up a proportion to find the total number of barrettes.
1/2 = 8/x
To solve for x, we can cross multiply:
2 * 8 = 1 * x
16 = x
Based on this calculation, Julia has a total of 16 barrettes.
(2/4)= 1/2
8 red barrettes = 1/2 of Julias collection
since half of Julia's barrettes are red, and she has 8 red barrettes you multiply 8*2 to get 16
(2 or (2/1) is the inverse fraction of (1/2))
to double check your answer..
16*(2/4)
