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}
