Final Answer:
a. The operation "select" corresponds to division, and multiplication.
b. The operation "select" corresponds to finding the percentage of a number.
c. The operation "select" corresponds to finding a part when a percentage is given.
d. The operation "select" corresponds to finding a percentage when a part is given.
Step-by-step explanation:
a. When the operation "select" is associated with division and multiplication, it refers to a calculation involving both of these operations. For example, if you select a number and then perform the operation "select," you might divide it by one number and multiply it by another.
b. If the operation "select" involves percent and number, it indicates finding a percentage of a given number. For instance, selecting 20% of 150 involves multiplying 150 by 0.2.
c. When the operation "select" is related to part and percent, it means finding a part of a whole when a percentage of that part is given. For instance, if you select 30% of a total quantity, it represents finding the numerical value of 30% of that total.
d. Similarly, when the operation "select" involves part and percent, it implies determining the percentage when a part of the whole is given. For example, if you know a particular quantity is 40% of the total, the operation "select" in this context involves finding the percentage (40%).
In conclusion, understanding the operation "select" in these contexts provides clarity on the mathematical calculations involved, whether they include division, multiplication, finding percentages, or determining parts of a whole.
