Variables are taken from the first letter of the color, ex: green = g.

Given:
r = g
2r = b = y
Total =42

So then:
r+ r + 2r + 2r = 42
6r = 42
r = 7

y = 2r
y = 2(7)
14 of the 42 pencils were yellow.

it confuses me when i have to fill in the in between i just dont quite understand how to work it out please explain it clearly

prisoha [69]

Make the unknown numerator be x and unkown denominotor be y

We have : 7 - $\frac{x}{y}$ = 6 $\frac{4}{5}$

=> $\frac{x}{y}$ = 7 - 6 $\frac{4}{5}$

$\frac{x}{y}$ = $\frac{1}{5}$

So we need to fill in the box : $\frac{1}{5}$

If the answer is helpful, Brainliest please!
