If we take 771 to be the 100%, and increase it by 98%, thus 100% + 98% = 198.

now, if 771 is the 100%, what is the 198%?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
771&100\\
a&198
\end{array}\implies \cfrac{771}{a}=\cfrac{100}{198}\implies \cfrac{771\cdot 198}{100}=a$

The ratio of the height to the width of a packaging label is 5 to 19. If the height of the label is 1.5 inches, What is the widt

zhuklara [117]

Answer

Find out the what is the width .

To prove

Let us assume that x be the scalar multiple of the height and width of the packaging label .

As given

The ratio of the height to the width of a packaging label is 5 to 19.

If the height of the label is 1.5 inches .

Than the equation becomes

5x = 1.5

$x = \frac{1.5}{5}$

x = 0.3

Than

The width of a packaging label = 19 × 0.3

= $ 5.7

Therefore the width of the packaging label is $ 5.7 .
