Answer:
6
Explanation:
To solve this, divide 9 by 1 1/2.
To make this easier to divide, convert 1 1/2 into an improper fraction.
1 1/2 = 3/2
Dividing 9 by 3/2 is the same as multiplying 9 by 2/3
Multiply the numerators and denominators
[9 is the same as 9/1]
9 x 2 = 18
1 x 3 = 3
18/3 = 6
So, Emma can paint 6 rooms.
