Rolls are being prepared to go to the grocery stores divide 72 rolls into two groups so the ratio is 3 to 5

To find the

1. Add the different parts of the ratio together (3+ 5 = 8)
2. Divide the number of rolls by the parts of the ratio that were added together (72 ÷ 8 = 9)
3. Now multiply that number first by 3, which is the first part of the ratio (9 × 3 = 27)
4. Then do the same but multiply the number by 5, the second part of the ratio (9 × 5 = 45)

You've got your answer! 27 and 45

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b
