50% of a certain number is 39. What is the number?

1 answer:

8 0

Let that certain number be 'n'

50% (n) = 39

50% ⇒ 0.5

0.5 (n) = 39

Divide both sides by 0.5

0.5n = 39
/0.5 /0.5

n = 78.

So that certain number is actually 78! :)

CROSS CHECK:

50% of 78

0.5 × 78

= 39

Hope this helps! :)

Sophie [7]

Answer: 540

Step-by-step explanation:

Given: A polling company reported that 53% of 1018 surveyed adults said that rising gas prices are "quite annoying."

To find: The exact value of 53% of 1018.

$53\%\text{ of }1018 = \dfrac{53}{100}\times1018$ [we divide a percentage by 100 to convert it into a fraction of decimal]

$=\dfrac{53954}{100}=539.54\\\\\approx540$

Hence, the 540 adults said that rising gas prices are "quite annoying."

Thus, the exact value = 540

$\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{6\% of 12.75}}{\left( \cfrac{6}{100} \right)12.75}\implies 0.765~~\approx 0.77~~\textit{about 77 cents}$
