Question

Write to Explain-Lucy danced for an hour, practicing ballet, jazz, and tap. She practiced twice as long on jazz as tap. She practiced ballet as many minute as tap . Explain whether you have enough information to find the number of minutes she practiced tap. If so, write a number sentence

Answer 1

You do

minutes on tap = n
minutes on ballet = n (same as tap_
minutes on jazz = 2n

n + n+ 2n = 60 minutes
4n= 60 minutes   (now divided both sides by 4)
n = 15 minutes  2n = 30 minutes
tap = 15 minutes    ballet = 15 minutes and jazz = 30 minutes  - Total = 1 hour
