Answer: Our required values are \dfrac{9}{20}\ and\ 0.85 respectively.

Step-by-step explanation:

Since we have given that

0.45

We need to rewritten in fraction as simplest form:

So, it would be rewritten as

\dfrac{45}{100}=\dfrac{9}{20}

Similarly,

\dfrac{17}{20}

We need to rewritten in decimals.

So, it would be rewritten as

\dfrac{17\times 5}{20\times 5}=\dfrac{85}{100}=0.85

Hence, our required values are \dfrac{9}{20}\ and\ 0.85 respectively.

Correct answer get the BRAINLIEST ANSWER!
OLga [1]
Here is how I completed the problem:

I started by creating a ratio:

\frac{x}{0.18} + \frac{360}{0.10} = \frac{x+360}{0.15}

<em>Where 'x' is the desired amount of the 18% solution of sulfuric acid. 

</em>From here, I solved for 'x':
<em>
</em>\frac{0.10x}{0.018} + \frac{360(0.18)}{0.018} = \frac{x+360}{0.15}
\frac{0.10x}{0.018} + \frac{64.8}{0.018} = \frac{x+360}{0.15}
\frac{0.10x+64.8}{0.018} = \frac{x+360}{0.15}
0.15(0.10x+64.8) = 0.018(x+360)
0.015x+9.72 = 0.018x+6.48
0.003x = 3.24
x = 1080

∴You will need to add 1080ml of 18% Sulfuric Acid in order to obtain a 15% solution.
