Find the ratio y:x, if 3x=11y,
Aleks [24]

Answer:

3:11

Step-by-step explanation:

3x=11y

<u>Rearrange to the format of the ratio.</u>

11y = 3x

<u>Let's find </u><u>y/x</u><u>. </u><u>y/x</u><u> is </u><u>y:x.</u>

11y = 3x

<u>Divide both sides by </u><u>11</u><u>.</u>

11y/11 = 3x/11

y = 3x/11

<u>NOW LET'S DIVIDE BOTH SIDES BY </u><u>x</u><u> TO GET </u><u>x</u><u> AS THE DENOMINATOR OF </u><u>y</u><u>.</u>

y = 3x/11

y/x = (3x/11)/x

y/x = (3x/11) * 1/x

y/x = 3/11

Therefore, y:x = 3:11
