Mumz [18]

2 1/24

Rewriting our equation with parts separated

2/3+1+3/8

Solving the fraction parts

Find the LCD of 2/3 and 3/8 and rewrite to solve with the equivalent fractions.

LCD = 24

16/24+9/24=25/24

Simplifying the fraction part, 25/24,

25/24=1 1/24

Combining the whole and fraction parts

1+1+1/24=2 1/24
