Answer :
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.
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.
