46 x 0.05, since 5% = 0.05 (5 / 100 = 0.05)
46 x 0.05 = 2.3
<span>7/12 is 58.33% </span>
<span>How do we change fractions to percents? </span>
<span>The steps are too simple. </span>
<span>First, divide the numerator (the number at the top of the fraction) by the denominator (the number below the fraction). </span>
<span>In the case above, 7 is the numerator and 12 is the denominator. </span>
<span>So, 7 ÷ 12 = 0.58333 </span>
<span>Then, multiply the result by 100. 0.5833 x 100= 58.33 </span>
<span>Finally, add the percent (%) sign to the result. </span>
<span>Therefore, 7/12 is 58.33%. <span> </span></span>

Step-by-step explanation:
Answer: The concentration of X is
and the concentration of Y is
.
Step-by-step explanation:
Since we have given that
At 272 nm, absorbance = 0.215
At 327 nm, absorbance = 0.191
As we have given that
Compound X Compound Y
272 16400 3870
327 3990 6420
So, our equations becomes

By solving these two equations, we get that

Hence, the concentration of X is
and the concentration of Y is
.
