Question

Mark is painting a mural. He paints 1/5 wall in 2/3 hour. what is his rate per hour?
A: 3/10 wall per hour
B: 3/8 per hour
C: 2/5 per wall
D: 2/15 per wall
Someone please help me

Answer 1

For 2/3 hour, he painted = 1/5 wall
For 1 hour it would be: 1/5 / 2/3
 
We can re-write it as: 1/5 * 3/2 = 3/10 wall

So, your final answer is 3/10 wall

Hope it helped.
