Daniel can paint a house in 10 days, while his father can paint the same house in 6 days. If they work together, how long will t

Alex73 [517]

Answer:

3 $\frac{3}{4}$ days

Step-by-step explanation:

Let the amount of work be x.

Daniel:

10 days = x

1 day = $\frac{1}{10}$ x

Father:

6 days = x

1 day = $\frac{1}{6}$ x

Together:

1 day = $\frac{1}{10}$ x + $\frac{1}{6}$ x

= $\frac{6}{60}$ x + $\frac{10}{60}$ x

= $\frac{16}{60}$ x

= $\frac{4}{15}$ x

No. of days = $\frac{15}{15}$ x ÷ $\frac{4}{15}$ x

= $\frac{15}{15}$ x × $\frac{15}{4}$ x

= $\frac{225}{60}$

= 3 $\frac{3}{4}$
