2. Explanation
X and Y are whole numbers.
X% Y finds the remainder after you divide X by Y.

equals 2 and the remainder is 1). So, 7% 3 equals 1.

Step-by-step explanation:

MrRoyal

The remainder of a division is the whole number, after the complete division. The expression that finds the last digit of 1327 is: [tex]X \% 10[/tex]

Given that:

[tex]X = 1327[/tex]

To do this, we simply test the given options.

[tex]X \%2 = 1327 \% 2[/tex]

When 1327 is divided by 2,

The result is 663, remainder 1

So, we have:

[tex]X \%2 = 1[/tex]

[tex]X \%3 = 1327 \% 3[/tex]

When 1327 is divided by 3

The result is 442, remainder 1

So, we have:

[tex]X \% 3 = 1[/tex]

[tex]X \% 5 = 1327 \% 5[/tex]

When 1327 is divided by 5

The result is 265, remainder 2

So, we have:

[tex]X \% 5 = 2[/tex]

[tex]X \% 10 = 1327 \% 10[/tex]

When 1327 is divided by 10

The result is 132, remainder 10

So, we have:

[tex]X \% 10 = 7[/tex]

[tex]X \% 100 = 1327 \% 100[/tex]

When 1327 is divided by 100,

The result is 13, remainder 27

So, we have:

[tex]X \% 100 = 27[/tex]

Hence, the expression that finds the last digit is: [tex]X \% 10[/tex]

Because the result is 7
