Set up the problem as: y=number of yellow marbles & 4y=number of blue marbles. 40=y+4y or 40=5y or y=8. Therefore number of blue marbles is 4*8 = 32.

That's an odd question, isn't it?

In order for 4 red marbles to be one-third of a group and 3 blue marbles to make up one-fourth of the same group the number has to equal 12.
There has to be 12 marbles in the group. If 4 are red that is 1/3 of 12 and if 3 are blue that is 1/4 of 12. The rest can be any color. That is how you explain how four red marbles can make up 1/3 of a group of marbles and three blue marbles make up 1/4 of the same group :)

Depends on your nose, you have to try. Then dial 911.
it's the LCM of 18 and 42 18 = 2x32 42 = 2x3x7 LCM = 2x32x7 = 126
Yes you can be. For example some people are allergic to oranges (though technically you can slice it up and put it in your nose).
it means a number verses another number, like a fraction Here;s an example you have 10 white marbles, 3 blue marbles, and 7 green marbles. what is the ratio of green marbles to the total amount of marbles? hat you do is look at the green marbles, and in this case, there are 7. Now add up all the marbles, which is 20. Your ratio is then 7:20.
You hold the grips in one hand and use the long nose to remove or pick up items in hard to access holes or corners where fingers won't fit.
