Answer:
27/72
Step-by-step explanation:
27/72 is correct because it is not equal to the ration 3:8
A ratio shows us the number of times a number contains another number. The ratio that is not equivalent to gray square to total square is C, that is 21/60.
A ratio shows us the number of times a number contains another number.
As we can see that the total number of squares is 8, while the number of gray scales is 3. Therefore, the ratio of the gray scales to total square can be written as,
[tex]\rm \dfrac{Gray\ Square}{Total\ Square}= \dfrac{3}{8}[/tex]
Now, if the option is reduced then,
A.)
[tex]\dfrac{9}{24} = \dfrac{3 \times 3}{3 \times 8}=\dfrac38[/tex]
B.)
[tex]\dfrac{15}{40} = \dfrac{5 \times 3}{5 \times 8}=\dfrac38[/tex]
C.)
[tex]\dfrac{21}{60} = \dfrac{7 \times 3}{5 \times 3 \times 4}=\dfrac{7}{20}[/tex]
D.)
[tex]\dfrac{27}{72} = \dfrac{3 \times 3 \times 3}{3 \times 3 \times 8}=\dfrac38[/tex]
Thus, the ratio that is not equivalent to gray square to total square is C, that is 21/60.
