If the ratio of red roses to yellow roses is 4 to 6 and there are a total of 50 roses, how many of them are yellow?

30 yellow roses

Step-by-step explanation:

4:6 means that there are 10 parts all together

divide the total number of roses by the amount of parts.

50 divided by 10 is 5.

to find out red roses, do 5 times 4,

to find out yellow roses, do 5 times 6

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
