Natalya earns $7.50 an hour when she works for her mom at home. On Monday, she works for 1 1/2 hours grading papers. On Tuesday, she worked for 1 1/3 hours entering data, and on Wednesday, she worked for 1 3/12 hours organizing paperwork. How much was Natalya's total earnings in the 3 days?

Respuesta :

$7.50 x 3 = 22.5 (adding first 3 whole numbers, then the fractions)

1/2 of an hour is 30 minutes
1/3 of an hour is 20 minutes
3/12 of an hour is 15 minutes

That means that she worked for 4 hours and 5 minutes.
