Ramon earns $1,880 each month and pays $53.30 on electricity. To the nearest tenth of a percent, what percent of Ramon's earning
AfilCa [17]
<h2>Answer:</h2>

Each month, 2.8% Ramon's earnings are spent on electricity.

<h2>Step-by-step explanation:</h2>

You know, that 100 percent are his earnings - $1,880

Now, you need to find out, how much is 1%. You do that by dividing $1,880 by 100.

Now you have to divide the amount he pays on electricity - $53.3 by one percent of his earnings - $18.8

So, now you know, that he pays exactly 2.83511% of his earnings on electricity. But from assignment, you know, that it has to be rounded to the nearest tenth of a percent. The number is 2.8351. So we will round it to 2.8% ,because 3 is rounded down. (https://www.mathsisfun.com/rounding-numbers.html)

100% = $1,880

$1,880/100 = $18.8

$53.3/$18.8 = 2.83511

2.83511% ≈ 2.8%

2/0 = 32/48 = 30/0. What number shpuld come in place of the zeros?​
Anton [14]

Answer:

\sf \dfrac{2}{3}  = \dfrac{32}{48}  = \dfrac{30}{45}

<h3><u>For the 1st part</u></h3>

\sf \rightarrow \dfrac{2}{x} = \dfrac{32}{48}

\sf \rightarrow 2(48)= {32x}

\sf \rightarrow 32x= 96

\sf \rightarrow x = 3

<h3><u>For the 2nd part</u></h3>

<u />\rightarrow \sf \dfrac{32}{48} = \dfrac{30}{y}

\rightarrow \sf {32y} = 30(48)

\rightarrow \sf {32y} = 1440

\rightarrow \sf y = 45
