How do you solve #w+ \frac { 3} { 4} = 2\frac { 4} { 5}#?

Answer 1

Gianna Caruso

#color(blue)(w=2 1/20#

#w+3/4=2 4/5#

#:.w/1+3/4=14/5#

#:.(20w+15=56)/20#

multiply L.H.S. and R.H.S by 20

#:.20w+15=56#

#:.20w=56-15#

#:.20w=41#

#:.w=41/20#

#:.color(blue)(w=2 1/20#

To solve the equation $w + \frac{3}{4} = 2\frac{4}{5}$ , you need to isolate the variable $w$ . Subtract $\frac{3}{4}$ from both sides of the equation, then convert the mixed number $2\frac{4}{5}$ to an improper fraction. After that, simplify and solve for $w$ .
