Lea earned $24 babysitting. She spent ⅔ of that amount on a gift for her bestie, ¼ on snacks. What fraction of her earning is left? How much money does she have left?
Let the total amount earned be 1
Given
Amount on snacks = ¼
Amount on babysitting = ⅔
Required
Fraction left
Fraction left = Total -(snacks+babysitting)
Fraction left = 1-(1/4+2/3)
Fraction left = 1-(3+4/12)
Fraction left = 1-7/12
Fraction left = 5/12
Amount of money she has left = 5/12 × 24 = 5×2 = $10
