Sagot :

The question says, 12 yards to 20 feet. First let's convert the units. One yard is equal to 3 feet. So if we multiply, [tex]3\cdot 12=36\quad feet[/tex] . Now we will, divide 36 feet to 20 feet and we'll simplify. [tex]\frac { 36 }{ 20 } [/tex] both 36 and 20 are divisible by 4, that means 4 is their common factor. We can simplify by that. [tex]\frac { 36 }{ 20 } =\frac { 4\cdot 9 }{ 4\cdot 5 } =\frac { 4 }{ 4 } \cdot \frac { 9 }{ 5 } =1\cdot \frac { 9 }{ 5 } =\frac { 9 }{ 5 } [/tex] 

The answer is D. 9:5
