A grid that is shaded red and blue in the ratio 1 : 1/3 include the following: A. grid A.
In Mathematics and Euclidean Geometry, a ratio is a mathematical expression that denotes the proportion of two or more quantities with respect to one another and the total quantities.
Based on the information provided above, the ratio of red squares to blue squares can be written as follows;
Ratio = 1 : 1/3.
By multiplying the ratios by 9, the new ratio can be written as follows;
New ratio = 9 : 3
By critically observing the grids, we have the following;
Grid A ↔ 9 : 3 = 1 :1/3
Grid B ↔ 8 : 4 = 1 : 1/2
Grid C ↔ 7 : 5
Grid D ↔ 10 : 2 = 5: 1
Grid E ↔ 3: 9 = 1: 3
Grid F ↔ 6:6 = 1 : 1
