Question

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

Answers-
A.n =-12 2/3
B.n = 6 2/3
C.n = 8
D.n = -6/25

Answer 1

3/10 n-3 1/5=-1 1/5
convert mixed numbers to a improper fractions:3 1/5=16/5

`(3)/(10)n- (16)/(5)=-1* (1)/(5)`
convert mixed numbers to a improper fractions:1 1/5=6/5

`(3)/(10)n- (16)/(5)=- (6)/(5)`
add 16/5 to both sides

`(3)/(10)- (16)/(5)+ (16)/(5)=- (6)/(5)+ (16)/(5)`
simplify
3/10 n=2
multiply both sides by 10

`10* (3)/(10)n=2*10`
simplify
3n=20
divide both sides by 3

`(3n)/(5)= (20)/(3)`
simplify

`n= (20)/(3)`
