The Two-step equations with decimals and fractions exercise appears under the 7th grade (U.S.) Math Mission. This exercise practices solving equations requiring more than one step and using decimals and fractions.
Types of Problems[]
There is one type of problem in this exercise:
- Solve the equation: This problem provides a two-step equation that may use either decimals, fractions, or both. The user is asked to find the correct answer and write it in the space below the problem.
Solve the equation
Strategies[]
Knowledge of the properties of equality and comfort with decimals and fractions are encouraged to ensure success on this exercise.
- One general process that can be followed with linear equations is to distribute, collect like terms, add/subtract variables to the left and numbers to the right, then divide by an appropriate constant.
- One can also divide before distributing in problems with parentheses.
Real-life Applications[]
- Fractions are used in real life in many different ways, but they are most commonly used in the cooking, construction and science industries.
- Equations are ubiquitous in all fields of mathematics as well as having a myriad of applications in almost all academic fields. They aid in verifying several scientific theories as well as programming.
- Computers are also equation solvers. Computers were originally invented to solve equations over and over again instead of humans doing the calculations.
