Answer 8/9

Accuracy of decimals: Always enter the most accurate decimal value that the grid will accommodate. For example: Ananswer such as .8888. . . can be gridded as .888 or .889. Gridding this value as .8, .88, or .89 is considered inaccurateand therefore not acceptable. The acceptable grid-ins of 8/9 are:

Be sure to write your answers in the boxes at the top of the circles before doing your gridding. Although writing out theanswers above the columns is not required, it is very important to ensure accuracy. Even though some problems mayhave more than one correct answer, grid only one answer. Grid-in questions contain no negative answers.

Answer 8/9

Accuracy of decimals: Always enter the most accurate decimal value that the grid will accommodate. For example: Ananswer such as .8888 . . . can be gridded as .888 or .889. Gridding this value as .8, .88, or .89 is considered inaccurateand therefore not acceptable. The acceptable grid-ins of 8/9 are:

Be sure to write your answers in the boxes at the top of the circles before doing your gridding. Although writing out theanswers above the columns is not required, it is very important to ensure accuracy. Even though some problems mayhave more than one correct answer, grid only one answer. Grid-in questions contain no negative answers.

Answer 258 (no credit)

Note: Circles must be filled in correctly to receive credit. Mark only one circle in each column. No credit will be givenif more than one circle in a column is marked. Example:

Answer 8/9

Accuracy of decimals: Always enter the most accurate decimal value that the grid will accommodate. For example: Ananswer such as .8888 . . . can be gridded as .888 or .889. Gridding this value as .8, .88, or .89 is considered inaccurateand therefore not acceptable. The acceptable grid-ins of 8/9 are:

Be sure to write your answers in the boxes at the top of the circles before doing your gridding. Although writing out theanswers above the columns is not required, it is very important to ensure accuracy. Even though some problems mayhave more than one correct answer, grid only one answer. Grid-in questions contain no negative answers.
