Using this definition, we can find the opposite of -3 5/8 by moving the same distance from zero but in the opposite direction. To do this, we can start at -3 5/8 and move 3 5/8 units to the right (since 3 5/8 is the distance from -3 5/8 to zero) to get the opposite of -3 5/8, which is 3 5/8.
Similarly, we can find the opposite of 4 2/9 by moving the same distance from zero but in the opposite direction. To do this, we can start at 4 2/9 and move 4 2/9 units to the left (since 4 2/9 is the distance from 4 2/9 to zero) to get the opposite of 4 2/9, which is -4 2/9.
Therefore, the opposite of −3 5/8 is on the **right** side of zero on a number line as −3 5/8. The opposite of **4 2/9** is on the **left** side of zero on a number line as **4 2/9**.
Answer:
Step-by-step explanation:
The opposite of a number is its additive inverse, which means it's the number that, when added to the original number, results in zero. On a number line, the opposite of a number is located symmetrically on the other side of zero.
For the first part of your question:
The opposite of -3 5/8 is 3 5/8, and it is on the same side of zero on a number line as -3 5/8.
For the second part of your question:
The opposite of 4 2/9 is -4 2/9, and it is on the same side of zero on a number line as 4 2/9.
So, in both cases, the opposites are on the same side of zero as the original numbers.

Final answer:
The expression 12.3 - (-9.6) simplifies to the addition expression 12.3 + 9.6, which equals 21.9. The answer 21.9 could represent various things in different contexts, such as a sum of money, a distance, or a total number of items.
Explanation:
The expression 12.3 - (-9.6) is a mathematical operation involving two real numbers. The negative sign before the bracket signifies that you will be changing the sign of 9.6, which is negative, making it a positive number; this is due to the fact that subtracting a negative number is equivalent to adding a positive number.
As a result, the equation 12.3 - (-9.6) simplifies to 12.3 + 9.6. When these two numbers are added together, we end up with 21.9. This number might represent a variety of things, depending on the context of the problem. It could, for instance, represent a sum of money, a distance, or a total number of items.

Final answer:
The expression 12.3 – (-9.6) simplifies to 12.3 + 9.6, and further calculation gives us the answer 21.9. The meaning of these numbers with regards to the problem is not clear without further context.
Explanation:
The mathematical expression you provided, 12.3 – (-9.6) = 12.3 + 9.6, is basically removing the negative sign from -9.6 when subtracted, which turns it into a positive, therefore the expression can be simplified to addition. Now, to solve the expression, we simply add the numbers:
12.3 + 9.6 = 21.9
In terms of what the numbers mean in relation to the problem, it's not clear without additional context. However, in general terms, this might indicate a change in value, movement along a number line, or represent physical quantities such as distance, weight, or temperature.

The correct way to represent “the opposite of Liliana’s score is + 18.
What are additive and multiplicative inverses?
A number's additive inverse is a number that is added to it until the result is zero.
A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.
We know if 'a' is a number then the opposite of 'a' is '- a'.
Given, Liliana spells a word incorrectly and loses 18 points.
Looses 18 points is '- 18'.

There are 6 girls more than boys if the ratio of boys to girls in Mr. Bakers' social studies class is 2 to 3.
What is an arithmetic operation?
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The ratio of boys to girls in Mr. Bakers' social studies class is 2 to 3.
From the question:
2 + 3 = 5 parts
= 2/5 Boys
= 3/5 Girls
30(2/5) = 60/5 = 12 Boys
30(3/5) = 90/5 = 18 Girls
18 - 12 = 6 girls are more than boys
Thus, there are 6 girls more than boys if the ratio of boys to girls in Mr. Bakers' social studies class is 2 to 3.
