Question

Solve 3/10 n-3 1/5 = -1 1/5

Answer 1

3/10 n-3 1/5=-1 1/5
convert mixed numbers to a improper fractions:3 1/5=16/5
$\frac{3}{10}n- \frac{16}{5}=-1* \frac{1}{5}$
convert mixed numbers to a improper fractions:1 1/5=6/5
$\frac{3}{10}n- \frac{16}{5}=- \frac{6}{5}$
add 16/5 to both sides
$\frac{3}{10}- \frac{16}{5}+ \frac{16}{5}=- \frac{6}{5}+ \frac{16}{5}$
simplify 
3/10 n=2
multiply both sides by 10
$10* \frac{3}{10}n=2*10$
simplify 
3n=20
divide both sides by 3
$\frac{3n}{5}= \frac{20}{3}$
simplify 
$n= \frac{20}{3}$
Hope this helps
