Question

Each marble bag sold by Mary's Marble Company contains 5 blue marbles for every 4 purple

marbles. If a bag has 35 blue marbles, how many purple marbles does it contain?

Answer 1

The total no. of purple marbles will be:

`\boxed{ \underline{ \rm{28}}}`

Explanation:

It is given that for every 5 blue marbles, we have 4 purple marbles. And similarly we have to find for the no. of purple marbles for 35 blue marbles.

First, Let's divide these 35 blue marbles in groups of 5. We will get:

➝ 35 ÷ 5 = 7 groups

For each group of 5 marbles, there are 4 purple marbles. So for 7 groups, No. of purple marbles will be:

➝ 4 × 7 = 28 purple marbles.

And we are done! :D
