Answer 1

5:3.

Explanation:

Riley can dribble a basketball 50 times in 1/2 minute with her right hand and 30 times in 1/2 minute with her left hand.

Rate of her right hand is :
`(50)/((1/2))=100\ \text{per minute}`

Rate of her left hand is :
`(30)/((1/2))=60\ \text{per minute}`

Ratio of her right hand to her left hand dribbling rate :
`(100)/(60)=(5)/(3)`

So, the required ratio is 5:3.
