What number is 5% of 46?
saveliy_v [14]
46 x 0.05, since 5% = 0.05 (5 / 100 = 0.05)

46 x 0.05 = 2.3


<span>7/12 is 58.33% </span>
<span>How do we change fractions to percents? </span>
<span>The steps are too simple. </span>

<span>First, divide the numerator (the number at the top of the fraction) by the denominator (the number below the fraction). </span>
<span>In the case above, 7 is the numerator and 12 is the denominator. </span>

<span>So, 7 ÷ 12 = 0.58333 </span>

<span>Then, multiply the result by 100. 0.5833 x 100= 58.33 </span>

<span>Finally, add the percent (%) sign to the result. </span>

<span>Therefore, 7/12 is 58.33%.  <span> </span></span>

Marc ordered a rug. He gave a deposit of 30% of the cost and will pay the rest when the rug is delivered. If the deposit was $75
ra1l [238]

Answer: Marc still owes $175

Step-by-step explanation:

Let x represent the cost of the rug.

Marc ordered a rug and gave a deposit of 30% of the cost and will pay the rest when the rug is delivered. This means that the amount of money that he deposited

for the rug is

30/100 × x = 0.3 × x = 0.3x

If the deposit was $75, it means that

0.3x = 75

x = 75/0.3 = 250

The cost of the rug is $250

The amount that Marc still owes would be

250 - 75 = $175
