She paints her bedroom at the rate of 1.83 square feet per hour.

Given that,
Caitlin is painting her bedroom. She paints 42 square feet in 23 hours. At this rate, how many square feet can she paint in one hour is to be determined.

Here,
She paints 42 square feet in 23 hours.
Area painted = 42 square feet

What do I need to multiply to get my quotation

Answers

Answer:

6

Step-by-step explanation:

I believe this answer is 6 because you need to get common denominators first. So the fractions would be 6/8 and 1/8. Then you do the reciprocal which is 6/8 times 8/1. Then you multiply the numerators 6 and 8. Then the denominators 8 and 1. Then you do 48 divided by 8 (48/8) which is 6. You got this! :)
