Answer 1

Brian brought cookies to school one day for class. He brought two dozen. His class ate 1 1/2 dozen. How many where left? A: 6 cookies

Answer 2

Bryan weighed two pieces of metal for an experiment. The piece of copper weighed
`2(4)/(5)` pounds and the piece of zinc weighed
`4(3)/(5)`pounds. Calculate the total metal in pounds he used.

Solution:- Weight of copper metal=
`2(4)/(5)` pounds

Weight of zinc metal=
`4(3)/(5)`pounds

The total weight of the metal he used=
`2(4)/(5)+4(3)/(5)` pounds

To solve the sum first convert them into like improper fractions

`2(4)/(5)\rightarrow(2*5+4)/(5)=(14)/(5)`

`4(3)/(5)\rightarrow(5*4+3)/(5)=(23)/(5)`

Now, The total weight of the metal he used=
`(14)/(5)+(23)/(5)=(37)/(5)` pounds

Ans:- Bryan used
`(37)/(5)` pounds of metal.
