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%
C = (pi) * d
C / (pi) = d
30 / 3.14 = d
9.55 = d

Answer:
The desired divisor is n = 21
Step-by-step explanation:
Let that number be n. Then:
-15/56 -5
---------- = ---------
n 6
Through cross-multiplication we get:
(-15/56)*6 = -5n, which reduces to:
(-15)(7) = -5n, or 3(7) = n
The desired divisor is n = 21
