Answer:
It'd be 4/15
Step-by-step explanation:
The total marbles is 6, so for black it's 4/6, but it's not being put back in so for the next one, the denominator would be 5. For green it's 2/5
4/6 times 2/5 equal 4/15
Hope this helps!
Yes, since these are the fractions:
8/10 and 4/5
If you multiply the numerator and denominator of 4/5 by two, you get 8/10 which means they are equivalent.
