Inequations can be solved using multiple math operations. Here, students will learn to graph inequalities after solving them.

### Ratios and Proportion

Ratio and proportion are closely-related concepts. A ratio is a comparison between two quantities having the same unit. On the other hand, a proportion is an equation that states the equality between two ratios.

#### Ratios and ratio tables

We use ratios to compare two quantities of the same unit. For example, we use ratios to compare the number of apples to the number of oranges in a fruit basket. Students will learn to create a ratio table to express equivalent ratios.

#### Identifying proportional relationships

Proportions are equations that express the equality of two ratios. Seventh graders will learn to identify proportional relationships among quantities using different properties.

#### Graphs of proportional relationships

Proportional relationships can be represented as a graph by plotting the points in the ratio table in a coordinate plane and drawing a line through them.

#### Solving ratio and proportion problems using scale drawings

A scale drawing is a two-dimensional drawing that represents an object, reduced or enlarged by a specific factor.

### Percents

A percent is a number or a ratio expressed as a fraction of 100. We use percents to express scores, discounts, markup, and so on. Students will learn how to calculate percents by solving different problems in this free online math course.

#### Fractions, decimals, and percents

Fractions, decimals, and percentages are different ways of expressing the same quantity. Seventh graders will learn to interconvert fractions, decimals, and percents.

#### Percent to find the missing quantities

In this section, seventh grade math students will learn to find missing or unknown quantities using percents.

#### Percents of increase and decrease

A change in value can be expressed using percents. Students will learn separate formulas to calculate the percent increase and percent decrease of values.

Interest is the price gained when money is borrowed or the cost charged to lend money. Seventh graders will learn the formula used to calculate simple interest. Simple interest is a method to calculate interest.

### Probability

Probability is a branch of mathematics that deals with the numeric representation of how likely an event is to occur. Seventh grade math students are introduced to the concept of probability.

#### Probability

The chance or likelihood of an event occurring can be described mathematically using the concept of probability. Students will learn to find the probability of an event by using the concept of relative frequency. They will also solve seventh grade math problems based on the same concept.

#### Experimental and theoretical probability

Any two of the approaches can be used for finding the probability of an event occurring: experimental probability and theoretical probability. Seventh graders will learn both methods and the differences between them.

#### Compound events

A compound event consists of multiple simple events happening simultaneously or in succession. Here, 7th grade students will learn the method of calculating the probability of outcomes of a compound event.

#### Simulations in probability

A simulation is a virtual imitation of real-world events. We use simulations to replace real-world experiments when they are not feasible. Simulating events allows us to calculate the experimental probability without actually performing the experiment.

#### Cross sections of three-dimensional figures

A cross-section of a three-dimensional figure is a two-dimensional figure obtained by the intersection of a solid and a plane surface. In other words, it is the shape obtained by slicing a three-dimensional figure.
