  1. 3. Two ratios are equivalent if they have the same value when simplified.
  2. 4. A ratio compares two quantities by division. A ratio may be written using a colon, but is more often written as a fraction.
  3. 6. To make something smaller (a fraction: To put a fraction into a simplest form.)
  4. 8. expression An expression is a combination of individual terms separated by plus or minus signs. Numerical expressions combine numbers and operation symbols; algebraic.
  5. 10. For polygon a vertex is the point at which two line segments meet to form a “corner”.
  6. 11. Replacing one symbol with a number, variable, or another algebraic expression of the same value. Substitution does not change the value of the overall expression.
