Sammy is trying to determine how many triangles she can create out of a square grid that has a side of 12 inches. use the image below to determine the area of the triangle and how many she can cut out. triangle with height of 6 inches and base of 12 inches aligned at bottom of a 12 by 12 inch square grid.
the area of the triangle is 36 in2, so she can create only 2 triangles.
the area of the triangle is 72 in2, so she can create only 2 triangles.
the area of the triangle is 36 in2, so she can create only 4 triangles
.
the area of the triangle is 72 in2, so she can create only 4 triangles.

The answer is the area of the triangle is 36 in2, so she can create only 4 triangles. You find this by first figuring out the area of the square. 12x12=144. Then you calculate the area of one triangle.the triangle's dimensions are 6x12. 6x12=72 and because it's a triangle you divide this number by two to get the area of one triangle. 72/2=36. 36x4=144, so the area of one triangle is 36 and you can fit four in the original square.

5 7/8 - 2 9/10

we can make 5 7/8 into an improper fraction of 47/8

we can also make 2 9/10 into an improper fraction of 29/10

find a common multiple between the denominators 10 and 8 - the smallest would be 40

47/8 will be made into 235/40

29/10 will be made into 116/40

235/40 - 116/40 = 119/40

simplify 119/40 and you get 2 39/40

decimal form is 2.975
