Michelle is planting flowers in her garden. She wants the ratio of daisies to carnations to be 3 to 2. Michelle wants to plant a total of 30 flowers. How many daisies should she plant?

Answer 1

The ratio of daisies to carnations is 3 to 2, which means for every 3 daisies there are 2 carnations.
Let x be the number of daisies Michelle plants
The number of carnations she plants is (2/3)x
The total number of flowers is x+(2/3)x=30 flowers
(5/3)x=30 flowers
x=18 flowers
Michelle should plant 18 daisies. Answer: \boxed{18}.

Answer 2

Ross drives 396 miles in 6 hours. If Ross continues to drive at the same rate, how many miles can he drive in 12 hours?

Answer 3

Since Ross drives 396 miles in 6 hours, his rate of driving is 396 miles/6 hours = <<396/6=66>>66 miles/hour.
Therefore, Ross can drive 66 miles/hour * 12 hours = <<66*12=792>>792 miles in 12 hours. Answer: \boxed{792}.
