A.2/15




B.1/30




C.1/4




D.1/3

Answer 1

i would say A

Answer 2

okay so first add all the marbles in total

Answer 3

so its 30 in total; and they're asking for black marbles

Answer 4

so black marbles is 4, and toal is 30. so you have 4 out 30 chances of getting a black marble.

Answer 5

but youd have to cut it in half

Answer 6

4 : 30... now reduce.

Answer 7

right?^^^ since that isnt a choice

Answer 8

i know you have to reduce it

Answer 9

then divide both of them by 2 or you can just cut it in half by looking at it. so now it's 2 : 15.

Answer 10

That's your answer! A!!! 2 : 15!
