Answer:
30 5/6 square feet
Step-by-step explanation:
First you need to know how much she can paint in 1/5 hour. So you're going to be dividing mixed numbers. To do that you need to make 12 1/3 a fraction:
12*3=36
36+1=37
12 1/3= 37/3
Divide by 2. With fractions you flip the second and multiply
37/3 ÷ 2/1 = 37/3 *1/2
Multiply top by top bottom by bottom
37*1=37
3*2=6
37/6 is what she can paint in 1/5 hour
Now you need to multiply that by 5 (5/5= 1 which means a full hour)
So we use 5/1 to multiply by 5 in fraction form.
37/6 * 5/1
37*5=185
6*1=6
Now simplify (turn it back into a mixed number)
185/6= 185÷6
30 with a remainder of 5
