Answer:

33 blue marbles

Step-by-step explanation:

As we are finding only how many blue marbles are there, we can make the ratio 3:14 instead, 3 being the blue marbles and 14 being other colors. This ratio is 17 then. There are 187 marbles in the bag, and there are eleven 17s in 187 (this can be calculated by doing 187 ÷ 17 to get 11) so you just multiply 3 and 11 to get 33.

Hope this helps! :D

Answer:

33 blue marbles

Step-by-step explanation:

sum up all the ratio

4+2+3+8=17

since we are looking for blue then we take a ratio of the blue marbles multiplied by the total number of marbles

3/17 *187

= 33
