Question

Nx4/5=3/4

Answer 1

Answer:

1. B

2. A

3. C

4. B

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.  

$N\frac{4}{5}=\frac{3}{4}\\\\\frac{5}{4}*\frac{4}{5}N=\frac{3}{4}*\frac{5}{4}\\\\N=\frac{15}{16}$

2.  

$\frac{D}{5}=4\\\\\frac{5}{1} *\frac{D}{5}=4*\frac{5}{1}\\\\D=20$

3.  

$2\frac{1}{4}r=10\\\\\frac{9}{4}r=10\\\\\frac{4}{9} *\frac{9}{4}r=10*\frac{4}{9}\\\\r=\frac{40}{9} \\\\r=4\frac{4}{9}$

4.  

$\frac{h}{26}=5\\\\\frac{26}{1} *\frac{h}{26}=5*\frac{26}{1}\\\\h=130$

5.  

$\frac{6}{7}k=6\\\\\frac{7}{6} *\frac{6}{7}k=6*\frac{7}{6}\\\\k=\frac{42}{6} \\\\k=7$
