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

grigory [225]

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

Tucker was asked to solve the equation 5x + 3 = 6x + 1. He did not know if his first step should be to add 5 negative x-tiles, o

Fittoniya [83]

It does not matter which he does first. Either way, zero pairs will be created on both sides, which will isolate the variable to determine x. Adding the x-tiles and then the unit tile, or visa versa, will give the same solution.

Please help i need answer for test

Korvikt [17]

Answer:

He did the complete opposite of what he needed to do

Step-by-step explanation:

The error is that when you need to find x - intercept, you need to replace the value of y with zero, not the y value.

Cause otherwise, what he did here is to find the y - intercept

If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
