5. A
Step-by-step explanation:
To solve equations with fractions, convert from a mixed number to an improper fraction then use the inverse. The inverse of a fraction is multiplying by the reciprocal of the fraction on both sides.
1.
[tex]N\frac{4}{5}=\frac{3}{4}\\\\\frac{5}{4}*\frac{4}{5}N=\frac{3}{4}*\frac{5}{4}\\\\N=\frac{15}{16}[/tex]
2.
[tex]\frac{D}{5}=4\\\\\frac{5}{1} *\frac{D}{5}=4*\frac{5}{1}\\\\D=20[/tex]
3.
[tex]2\frac{1}{4}r=10\\\\\frac{9}{4}r=10\\\\\frac{4}{9} *\frac{9}{4}r=10*\frac{4}{9}\\\\r=\frac{40}{9} \\\\r=4\frac{4}{9}[/tex]
4.
[tex]\frac{h}{26}=5\\\\\frac{26}{1} *\frac{h}{26}=5*\frac{26}{1}\\\\h=130[/tex]
5.
[tex]\frac{6}{7}k=6\\\\\frac{7}{6} *\frac{6}{7}k=6*\frac{7}{6}\\\\k=\frac{42}{6} \\\\k=7[/tex]
