An adult turtle weighed 3 3/4 ounces. how much would 3 adult turtles weigh?

If one adult turtle weighs 3 3/4 ounces, then three adult turtles will weight three times that amount. Make sense? So:

3 3/4 + 3 3/4 + 3 3/4

and if 3 3/4 is the same as saying 15/4, then:

15/4 + 15/4 + 15/4

and that is the same as saying:

15/4 * 3

so:

15 times three is 45 (15 + 15 + 15)

and 4 stays the same.

The subtotal weight is 45/4.

Now we need to simplify.

Since a fraction is just a division problem, we can just say: 45 divided by 4.

Which is 11.25 ounces.

Back in fraction form that is 11 1/4 ounces.
