Julia collects colored beads for craft projects. Of Julia’s beads,
4/ 9
are silver,
1/5
are gold, and
1 /4
are blue. The rest of the beads are red. Which expression gives the closest estimate of the fraction of red beads Julia has?
The answer is 1-2/5-1/5-1/5; how did they get this
no choices listed, but 4/9 + 1/5 + 1/4 = 161/180
So, the remaining 19/180 are red.
That's a little more than 1/10 (18/180)
I need help ok
To find the fraction of red beads, we need to subtract the fractions of silver, gold, and blue beads from 1.
So, the expression to find the fraction of red beads is:
1 - (4/9 + 1/5 + 1/4)
Let's simplify this expression step by step:
First, find the common denominator for 9, 5, and 4, which is 180. Multiply the numerators and denominators accordingly:
1 - ((4/9) * (20/20) + (1/5) * (36/36) + (1/4) * (45/45))
Simplifying further:
1 - (80/180 + 36/180 + 45/180)
Now, we can add the fractions:
1 - (161/180)
To subtract fractions, we need to find a common denominator, which is 180 in this case:
1 * (180/180) - (161/180)
Subtracting the fractions:
180/180 - 161/180 = 19/180
Therefore, the expression (1 - (4/9 + 1/5 + 1/4)) simplifies to the fraction 19/180.
So, the closest estimate of the fraction of red beads Julia has is 19/180.
