An artist can paint 4 painting in 2 hours. what is the artist’s unit rate?

All we have to do here is divide 4 by 2

4 ÷ 2 = 2

Therefore, the artist can paint 2 paintings an hour making the unit rate, 2 paintings per hour.

Hope this helps

Since he can paint four paintings in two hours we must find how many paintings he can create in one hour. So if we divide the numerator and denominator by two, we get that he can paint two paintings in one hour. His unit rate is 2:1. 

4:2 divide by two to make the denominator 1

2:1 solution has 1 in the denominator

Hope this helped.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

answer: check all that apply, where the options?
