Final answer:
To find out what number 3 thousands (3,000) needs to be divided by to result in 3 tens (30), we can set up the division 3,000 divided by X equals 30 and solve for X, which results in 100.
Step-by-step explanation:
To solve the problem of 3 thousands divided by what number equals 3 tens, we first need to understand the numerical value of 3 thousands and 3 tens. Three thousands is 3,000 and three tens is 30. To find the number that 3,000 must be divided by to equal 30, we use the division operation.
Dividing 3,000 by a certain number should give us 30, therefore, we write it as an equation: 3,000 ÷ X = 30. To find X, we can rearrange this equation to X = 3,000 ÷ 30. Performing the division gives us 100 as a result. Therefore, 3,000 divided by 100 equals to 30.
In terms of dividing each number by the number of moles or in questions involving, say, resistors in parallel, understanding division is crucial. This skill translates across various disciplines, including sciences and engineering.
