Answer:

Step-by-step explanation:

Work done by Kayla in 1 hour = 1/15

Work done by Jennifer in 1 hour = 1/16

Work done by both Kayla and Jennifer = \frac{1}{15}+\frac{1}{16}

                 = \frac{1*16}{15*16}+\frac{1*15}{16*15}\\\\=\frac{16}{240}+\frac{15}{240}\\\\=\frac{31}{240}\\

Hours taken  by both = 240/31 = 7  23/31 hours

igomit [66]
Let’s remember the most basic thing in percentages, the equation.

Percent x Whole = Part.

We know the whole, and the part, but we are trying to find the percent, so we have to divide the two, first turn your whole and part into a decimal.

Percent x 0.4 = 0.18, so we divide 0.18 by 0.4

0.18/0.4 = 0.45

0.45 = 45%
