Question

The sparkling house cleaning company has cleaned 28 houses this week. If this number represents 40% of the total number of houses the company is contracted to clean,how many total houses will the company clean by the end of the week

Answer 1

70 houses

Explanation:

40×2=80

If you multiply the 40% by 2 you get 80%

Multiply the 28 by 2 to get your 80% for houses

28×2= 56

56 houses=80%

You need 20% to get your 100%, but at the beginning you were only given 40%. Divide your 40% (28) by 2 to get your 20% and add that to 56

28÷2=14

14+56=70
