Do these ratios form a proportion? 20 pedestrians : 2 seconds 10 pedestrians : 1 second Choices: (A)yes (B)no

Write Ratio in Fraction Form: Write the ratio 20 pedestrians for 2 seconds in fraction form. text(Pedestrians) / text(Seconds) = 20 / 2 Fraction form of the first ratio: 20 / 2Simplify Fractions: Write the ratio 10 pedestrians for 1 second in fraction form. text(Pedestrians) / text(Seconds) = 10 / 1 Fraction form of the second ratio: 10 / 1Check for Proportion: Simplify both fractions to find if they are equivalent. First fraction: 20 / 2 = 10 Second fraction: 10 / 1 = 10 Both simplified fractions are equal.Since both simplified fractions are equal, the ratios form a proportion.

Q. Do these ratios form a proportion?

\newline

20

pedestrians :

2

seconds

\newline

10

pedestrians :

1

second

\newline

Choices:

\newline

(A)yes

\newline

(B)no

Write Ratio in Fraction Form: Write the ratio $20$ pedestrians for $2$ seconds in fraction form. $\newline$ text(Pedestrians) / text(Seconds) = $\frac{20}{2}$ $\newline$ Fraction form of the first ratio: $\frac{20}{2}$
Simplify Fractions: Write the ratio $10$ pedestrians for $1$ second in fraction form. $\newline$ $\text{Pedestrians} / \text{Seconds} = \frac{10}{1}$ $\newline$ Fraction form of the second ratio: $\frac{10}{1}$
Check for Proportion: Simplify both fractions to find if they are equivalent. $\newline$ First fraction: $\frac{20}{2} = 10$ $\newline$ Second fraction: $\frac{10}{1} = 10$ $\newline$ Both simplified fractions are equal.
Check for Proportion: Simplify both fractions to find if they are equivalent. $\newline$ First fraction: $\frac{20}{2} = 10$ $\newline$ Second fraction: $\frac{10}{1} = 10$ $\newline$ Both simplified fractions are equal.Since both simplified fractions are equal, the ratios form a proportion.
