Front

Precipitation

Back

The amount of water, in the form of rain, snow, sleet, or hail, that falls to the ground. It is measured in units such as millimeters or inches.

Front

Difference between decimals

Back

To find the difference between two decimal numbers, subtract the smaller number from the larger one. Example: 0.76 - 0.49 = 0.27.

Front

Fraction representation

Back

A fraction represents a part of a whole. It is expressed as a/b, where 'a' is the numerator and 'b' is the denominator.

Front

Total rainfall calculation

Back

To find the total rainfall over a period, add the amounts of rain that fell each day.

Front

Ratio of Rainfall to Evaporation

Back

A ratio compares two quantities. In this case, it compares the amount of rainfall to the amount of water lost to evaporation.

Front

Algebraic expression for rainfall

Back

An algebraic expression models a situation. Example: R = 3t² + 2t + 5 models rainfall in mm based on weeks.

Front

Evaluating a quadratic expression

Back

To evaluate a quadratic expression, substitute the value of the variable into the expression and simplify.

Front

Runoff definition

Back

Runoff is the amount of water that flows over the ground surface after precipitation, calculated as rain fallen minus water absorbed.

Front

Multiplication of numbers

Back

Multiplication is a mathematical operation where a number is added to itself a certain number of times. Example: 3 * 2 = 6.

Front

Bucket capacity calculation

Back

To find the amount of water a bucket can hold, calculate the fraction of its total capacity. Example: 1/2 of 16ml = 8ml.
