630 red marbles

420 yellow marbles

210 purple marbles

because 1260 x 1/2 = 630, 1260 x 1/3 = 420, 1260 x 1/6 = 210

What mixed number is equivalent to 18/8
sukhopar [10]
The mixed number to 18/8 is 2 and 1/4
To find this out you multiply 8 to get to 18, yet 8 only goes to 16 before going over 18, so 8 can multiply 2 times.
The 2 will be your whole number 
and since there is 2 numbers left (18-16=2) that would be the numbers left over giving you 2 2/8.
yet the 2/8 can be simplified to 1/4 giving you 2 1/4 as your answer.
Hoped this helped!
