The colony of penguins travel 3/5 of a kilometer a day. How many kilometers will they travel in a week.

4 1/5

Step-by-step explanation:

(2*3 is the same as 2x3 in multiplication)

Since in a week there are 7 days, you multiply the number of days to the distance walked per day. Which is 7 * (3/5), or (3/5) * 7

So (3/5) * 7=4 1/5 or 4.2

(3/5) * 7 equals

(3/5) + (3/5) + (3/5) + (3/5) + (3/5) + (3/5) + (3/5) = (21/5)

There are four 5's in 21, so it is 4 wholes.

4 an the remaining 1 over 5

=4 1/5
