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:
Bryan weighed two pieces of metal for an experiment. The piece of copper weighed \(2\frac{4}{5}\) pounds and the piece of zinc weighed \(4\frac{3}{5}\)pounds. Calculate the total metal in pounds he used.
Solution:- Weight of copper metal= \(2\frac{4}{5}\) pounds
Weight of zinc metal=\(4\frac{3}{5}\)pounds
The total weight of the metal he used=\(2\frac{4}{5}+4\frac{3}{5}\) pounds
To solve the sum first convert them into like improper fractions
\(2\frac{4}{5}\rightarrow\frac{2\times5+4}{5}=\frac{14}{5}\)
\(4\frac{3}{5}\rightarrow\frac{5\times4+3}{5}=\frac{23}{5}\)
Now, The total weight of the metal he used=\(\frac{14}{5}+\frac{23}{5}=\frac{37}{5}\) pounds
Ans:- Bryan used \(\frac{37}{5}\) pounds of metal.
