Simplify the ratio 154:132 in its simplest form
marissa [1.9K]

Answer:

The simplified ratio is<em> 7:6</em>

Step-by-step explanation:

First we have to find the <em>GCF</em> of <em>both 154 and 132</em>.  Since the <em>GCF is 22</em>, we will <em>divide 154 by 22</em> and we get<em> 7</em>.  Now <em>divide 132 by 22 </em>and we get <em>6.</em>  Therefore, the simplest form or the ratio 154:132 is <em>7:6.</em>

Mingfa says, "My sister and I have $130 altogether. If my mother gives me another
quester [9]

Given:

Total amount of Mingfa and her sister = $130

If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.

To find:

How much money does Mingfa actually have?​

Solution:

Let, Mingfa have $x and her sister has $y initially. Then,

x+y=130                ...(i)

If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.

x+10=3y              ...(ii)

Substitute the value of x from (ii) in (i).

(3y-10)+y=130

4y=130+10

4y=140

Divide both sides by 4.

y=35

Putting y=35 in (i), we get

x+35=130

x=130-35

x=95

Therefore, Mingfa have $95.
