Susan can pick 4 pounds of coffee beans in an hour or gather 2 pounds of nuts. Tom can pick 2 pounds of coffee beans in an hour
natima [27]

Answer:

144

Step-by-step explanation:

Susan can pick 4 pounds of coffee beans in an hour.  Tom can pick 2 pounds of coffee beans in an hour.  Together, they can pick 6 pounds of coffee an hour.

4 + 2 = 6

There are 24 hours in a day.  Multiply the time by the amount that can be picked to find the answer.

24 × 6 = 144

Together, the maximum number of pounds of coffee beans the can pick in a day is 144 pounds.

Determine the quotient: 2 4/7 ÷ 1 3/6
Scilla [17]

First we must change these numbers to improper fractions:

2\frac{4}{7}=\frac{18}{7}

1\frac{3}{6}=\frac{9}{6}

So then we set it up:

\frac{18}{7} ÷ \frac{9}{6}

When we divide fractions like this, we must flip the second fraction and change the sign from division to multiplication like so:

\frac{18}{7}*\frac{6}{9}

Then we solve:

\frac{108}{63}

Then if we divide the numerator and the denominator by 9, we get:

\frac{12}{7} or, in mixed-number form, 1\frac{5}{7}.
