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 give the closest estimate of the fraction of red beads julia has?
i need an explanation on how to solve it

19 red beads

Step-by-step explanation:

We first need to find a common denominator of 4/9, 1/5 and 1/4.

The common denominator is 180. Like in an expression, what we do to one side we have to do to the other.

Silver - 180/9 = 20 ; 20*4 = 80 so there are roughly 80 sliver beads.

Gold - 180/5 = 36 ; 36*1 = 36 so there are roughly 36 gold beads.

Blue - 180/4 = 45 ; 45*1 = 45 so there are roughly 56 blue beads.

180 - (silver+gold+blue) = red beads

180-161 = 19 red beads b/c >

80+36+45+19 = 180
