Let r = # of red marblesLet 2r = # of blue marbles ... (1/2 as many red as blue, means blue is twice the red)Let r+8 = # of yellow marbles ... (8 more than the red) Total is 56 ... our equation is r + 2r + r + 8 = 56 4r + 8 = 56 4r = 56 - 8 4r = 48 r = 12 There are 12 red marbles.There are 24 blue marbles.There are 20 yellow marbles.

Explanation: I did it in decimals because I didn’t know if your assignment required fraction or decimal. 5 4/7= 5x7=35+4=39/7 so this means 5 4/7 is equal to 39/7. -2 2/5= -2x5=-10+2=-8/5. So it comes out to 39/7x-8/5.
