Ronald spent the day making a painting for his friend. at the end of the day, ronald finished 1/4 of the painting. if he is able to finish as much of the painting each day he works, how long will it take him to make 2 whole paintings?

The rate of Ronald to do a work in a day is 1/4 of the painting. The problem can be done using ratio and proportion.

In 1 day = 1/4
It will take him 4 days to finish 1 painting.
So, it will going to take him 8 days to finish 2 whole paintings.

1/4 + 1/4 + 1/4 + 1/4 = 1 painting = 4 days
1/4 + 1/4 + 1/4 + 1/4 = 1 painting = 4 days
