Question

Denise mixed 1 4/5 ounces of blue paint with 2 1/10 ounces of yellow paint. How many ounces of paint did Denise mix?

Answer 1

Answer: The answer is
`3(9)/(10)~\textup{ounces}.`

Step-by-step explanation: Given that Denise is making a paint mixture in which he is adding blue paint and yellow paint in the following proportions.

Ounces of blue paint used by Daniel is given by

`P_b=1(4)/(5)=(9)/(5)~\textup{ounces}.`

And ounces of yellow paint used is given by

`P_y=2(1)/(10)=(21)/(10)~\textup{ounces}.`

Therefore, total ounces of paint used by Daniel is

`P=P_b+P_y=(9)/(5)+(21)/(10)=(39)/(10)=3(9)/(10)~\textup{ounces}.`

Thus, the number of ounces of paint used is
`3(9)/(10)~\textup{ounces}.`

Answer 2

Hence total 3.9 ounces of paint was used to make the mixture.

Explanation:

Denise mixed
`1(4)/(5)` ounces of blue paint with
`2(1)/(10)` ounces of yellow paint.

Now we are asked to find how many ounces of paint did Denise mix.

i.e. we are asked to find the total number of paint used to form the mixture.

We know that:

`1(4)/(5)=(9)/(5)` and
`2(1)/(10)=(21)/(10)`

Hence total paint used=
`(9)/(5)+(21)/(10)`

=
`(39)/(10)=3.9`

Hence total 3.9 ounces of paint was used to make the mixture.
