Concept explainers

A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition

Question

Definition Definition Arithmetic method in which the value of a single unit is found from the value of the given units. Once the value of a single unit is known, then we can then find the value of the required units by multiplying the single value unit with the required number of units; alternatively, if the value of a certain number of units is known, we may find the required number of units after dividing the value given by the value of a single unit. Example. You're at the grocery store and see a billboard that says 10 oranges for $6. It's unusual, however, to always buy exact amount advertised. To calculate the exact price, the unitary method is used. To know the exact price of 8 oranges, you need to find the price of one orange, and then you can multiply that price by 8 to know the cost of 8 oranges. In this case, an orange = $6/10, or $0.60 per orange. Eight oranges will cost 8 * $0.60, or $4.80.

Chapter 0.1, Problem 12E

To determine

To convert meter to kilometer

Expert Solution & Answer

Answer to Problem 12E

3.1km

Explanation of Solution

Given information: The measurement is given as 3100m

Formula Used:

Unitary method 1m=0.001km

Calculation:

Since, 1m=0.001km To convert m to km divide the value by 1000

Now, divide 3100 with 1000

3100m=31001000km

This gives the answer as 3.1km

Conclusion- Hence, the complete sentence is 3100m=3.1km
