MA.6.AR.2.4

Determine the unknown decimal or fraction in an equation involving any of the four operations, relating three numbers, with the unknown in any position.

Examples

Given the equation begin mathsize 12px style 9 over 8 equals x minus 1 over 8 end style, x can be determined to be begin mathsize 12px style 10 over 8 end style because begin mathsize 12px style 10 over 8 end style is begin mathsize 12px style 1 over 8 end style more than begin mathsize 12px style 9 over 8 end style.

Clarifications

Clarification 1: Instruction focuses on using algebraic reasoning, drawings, and mental math to determine unknowns.

Clarification 2: Problems include the unknown and different operations on either side of the equal sign. All terms and solutions are limited to positive rational numbers.
