A bag has green and purple marbles. Two-fifths of the marbles are green, and the rest are purple.
Musya8 [376]

The number of purple marbles in the bag are; 201 purple marbles

<h3>How to work out fraction of bar model?</h3>

We are told that Two-fifths of the marbles are green, and the rest are purple.

A) The image attached shows the bar model where the shaded parts denote the purple marble while the unshaded parts denote the green marbles.

B) We are told that there are 134 green marbles.

If the total number of marbles are x. Then;

(2/5)x = 134

x = 134 * 5/2

x = 335 marbles

Thus;

Purple Marbles = (3/5) * 335 = 201 purple marbles
