What is a ratio?

Back

A ratio is a relationship between two numbers that shows how many times the first number contains the second. For example, the ratio of blue pens to red pens is 2:1.

How do you find the ratio of two quantities?

Back

To find the ratio of two quantities, divide each quantity by the greatest common factor. For example, if there are 12 blue pens and 6 red pens, the ratio is 12:6, which simplifies to 2:1.

How do you calculate the distance between two points on a coordinate grid?

Back

To calculate the distance between two points (x1, y1) and (x2, y2), use the formula: Distance = |y2 - y1|.

What is the average temperature?

Back

The average temperature is the sum of all temperatures divided by the number of temperatures. For example, if the temperatures are 10°C, 12°C, and 14°C, the average is (10 + 12 + 14) / 3 = 12°C.

What is an expression in mathematics?

Back

An expression is a combination of numbers, variables, and operators (like +, -, *, /) that represents a value. For example, 6n is an expression where n is a variable.

How do you evaluate an expression?

Back

To evaluate an expression, substitute the value of the variable into the expression and perform the operations. For example, for 6n when n=7, substitute 7 to get 6*7 = 42.

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the grid is represented by an ordered pair (x, y).

What does it mean for a temperature to be lower than another?

Back

A temperature is lower than another if its numerical value is less. For example, 5°C is lower than 10°C.

What is the significance of the x-axis and y-axis in a coordinate grid?

Back

The x-axis is the horizontal line, and the y-axis is the vertical line. They are used to locate points in the coordinate plane.
