Question

In your marble collection, 4/7 off the marbles are blue and 4/21 of the marbles are red. How many times more blue marbles do you have then red marbles?

Answer 1

convert 4/7 to ?/21 which is times 3, therefore, it is 12/21 versus 4/21. 12-4= 8 and so the answer is 8/21 more blue than red.

Answer 2

3 times more.

Explanation:

We have been given that in a marble collection, 4/7 off the marbles are blue and 4/21 of the marbles are red.

To solve our given problem, we will divide amount of blue marbles by amount of red marbles as:

`(4)/(7)/ (4)/(21)`

Convert to multiplication problem by flipping the 2nd fraction:

`(4)/(7)* (21)/(4)`

`(4* 21)/(7* 4)`

`(1* 3)/(1* 1)`

`3`

Therefore, blue marbles are 3 times more than red marbles.
