Answer:
d = 15
Step-by-step explanation:
Divide the numbers
[tex]\frac{20}{16} =\frac{d}{12}[/tex]
[tex]\frac{5}{4} =\frac{d}{12}[/tex]
Multiply all terms by the same value to eliminate fraction denominators
[tex]12*\frac{5}{4} =12*\frac{d}{12}[/tex]
Cancel multiplied terms that are in the denominator
[tex]12*\frac{5}{4} =d[/tex]
Multiply the numbers
[tex]15=d[/tex]
Move the variable to the left
[tex]d=15[/tex]
Hence, d= 15.
