The value of y when x = 5.25 is 210.
Given that the value of y varies directly with x.
When y = 30, x = 0.75.
We need to find the value of y when x = 5.25,
If the value of y varies directly with x, it means that the relationship between y and x can be expressed as:
y = kx
Where "k" is the constant of proportionality. To find the value of "k," we can use the given information:
When y = 30, x = 0.75:
30 = k × 0.75
Now, solve for "k":
k = 30 / 0.75
k = 40
Now that we have the value of "k," we can use it to find the value of y when x = 5.25:
y = k x
y = 40 × 5.25
y = 210
So, when x = 5.25, the value of y is 210.

The answer is 817.
Further explanation
Problem: given 4,083,817.
Question: what are the 3 digits in the unit period.
This is a problem with place value. Given 4,083,817 which is a large number in the standard form.
The digits in large numbers are in groups of three places, i.e.,
The groups are called periods, i.e.,
Commas are typically used to separate the periods.
Let's set the place values from 4,083,817 consecutively as follows.
Let us say in word form: four million eighty-three thousand eight hundred seventeen.
Hence, three digits in the units period are 817.
Keywords: the units period, 3 digits, 4,083,817, a large number, standard form, millions, thousands, hundreds, tens, ones, place value, four, eighty-three, seventeen, three, number form
Three digits in the units period are 817.
Given that,
A number is, 4,083,817.
Since, A number 4,083,817 which is a large number in the standard form.
The digits in large numbers are in groups of three places, i.e.,
hundreds,
tens,
ones (or units).
Now, The groups are called periods, i.e.,
millions period
thousands period
ones or units period
Commas are typically used to separate the periods.
Hence, the place values from 4,083,817 consecutively as follows.
In the millions period: 4 ones.
In the thousands period: 0 hundred thousands, 8 ten thousands, 3 one thousands.
In the units period: 8 hundreds 1 tens 7 ones.
Hence, in word form: four million eighty-three thousand eight hundred seventeen.
Hence, three digits in the units period are 817.
