Final answer:
To convert Janice's jump rope length from 5 4/10 to a mixed number in hundredths, multiply the fraction part (4/10) by 10/10 to get 40/100, making the length 5 40/100 feet.
Step-by-step explanation:
Janice's jump rope is 5 4/10 feet long. To rename the length of the rope as a mixed number in hundredths, we first convert the fraction part of the mixed number into hundredths.
The fraction 4/10 can be converted to hundredths by multiplying both the numerator and the denominator by 10. So, 4/10 times 10/10 equals 40/100. Therefore, Janice's jump rope is 5 and 40/100 feet long when expressed in hundredths.
The length of Janice's jump rope in hundredths is 5 40/100 feet.
