Question

Select all the ratios that are equivalent to the ratio 12:3. explain how you know( show multiplication or division)

Answer 1

Answer:

C 4:1

D 24:6

F 1200:300

Step-by-step explanation:

The given ratio is  $\frac{12}{3}$

Simplify

Divide by 3 both numerator and denominator

$\frac{4}{1}$

Verify each case

case A) we have

$\frac{6}{1}$

Compare with the given ratio

$\frac{6}{1} \neq \frac{4}{1}$

therefore

The ratio is not equivalent

case B) we have

$\frac{1}{4}$

Compare with the given ratio

$\frac{1}{4} \neq \frac{4}{1}$

therefore

The ratio is not equivalent

case C) we have

$\frac{4}{1}$

Compare with the given ratio

$\frac{4}{1}=\frac{4}{1}$

therefore

The ratio is equivalent

case D) we have

$\frac{24}{6}$

Simplify

Divide by 6 both numerator and denominator

$\frac{4}{1}$

Compare with the given ratio

$\frac{4}{1}=\frac{4}{1}$

therefore

The ratio is equivalent

case E) we have

$\frac{15}{6}$

Simplify

Divide by 3 both numerator and denominator

$\frac{5}{2}$

Compare with the given ratio

$\frac{5}{2} \neq \frac{4}{1}$

therefore

The ratio is not equivalent

case F) we have

$\frac{1,200}{300}$

Simplify

Divide by 300 both numerator and denominator

$\frac{4}{1}$

Compare with the given ratio

$\frac{4}{1}=\frac{4}{1}$

therefore

The ratio is equivalent

case G) we have

$\frac{112}{13}$ ----> irreducible

Compare with the given ratio

$\frac{112}{13} \neq \frac{4}{1}$

therefore

The ratio is not equivalent
