6.RP.1 6th Grade Math EOG Review

Enzo makes a pattern using square and triangular tiles. He uses 3 triangular tiles for every 2 square tiles. In total, Enzo uses 300 tiles. Which statement describes a correct method for determining the number of triangular tiles Enzo uses in his pattern?

• A. Multiply 300 by 3/2, the ratio of the number of triangular tiles to the number of square tiles, to find that Enzo uses 450 triangular tiles.

• B. Multiply 300 by 3/5, the ratio of the number of triangular tiles to the total number of tiles, to find that Enzo uses 180 triangular tiles.

• C. Multiply 300 by 2/3, the ratio of the number of square tiles to the number of triangular tiles, to find that Enzo uses 200 triangular tiles.

• D. Multiply 300 by 5/3, the ratio of the total number of tiles to the number of triangular tiles, to find that Enzo uses 500 triangular tiles.

In science class, students are learning about molecules. They learn that an acetic acid molecule is made of 2 carbon atoms, 2 oxygen atoms, and 4 hydrogen atoms.

• There are twice as many carbon atoms as oxygen atoms, so the ratio of carbon atoms to oxygen atoms is 1 : 2.

• There are twice as many hydrogen atoms as carbon atoms, so the ratio of hydrogen atoms to carbon atoms is 2 : 1.

• There are twice as many hydrogen atoms as oxygen atoms, so the ratio of hydrogen atoms to oxygen atoms is 1 : 2.

• There are twice as many oxygen atoms as carbon atoms, so the ratio of oxygen atoms to carbon atoms is 2 : 1.
