Answer:

16 minutes

Step-by-step explanation:

If it takes 63 minutes to paint 9 walls then it means for every wall, it takes 63/9=7 minutes

Since it is 4 people working for 7 mins, the individual rate is 4/7 minutes per person

When we have 7 people, then the number minutes they take will be 7*4/7=4 minutes per wall

4 min per wall for 4 walls then total time will be 4*4=16 minutes

Simplify.<br><br> 7/8+(−2/3) divided by <br> 5/6
Sedaia [141]
7/8+(−2/3) divided by 5/6

(7/8 - 2/3)/(5/6)
=(21/24 - 16/24) / (5/6)
= (5/24)  /  (5/6)
= 5/24 * 6/5
= 6/24
= 1/4
