Examlex · Accepted Answer

The Answer is

1 \frac { 47 } { 72 }

; Find the LCD of 72 and then change the unlike denominators to like denominators.

\frac { 5 imes 9 } { 8 imes 9 } = \frac { 45 } { 72 }

;

\frac { 7 imes 6 } { 12 imes 6 } = \frac { 42 } { 72 }

;

\frac { 4 imes 8 } { 9 imes 8 } = \frac { 32 } { 72 }

;

\frac { 45 } { 72 } + \frac { 42 } { 72 } + \frac { 32 } { 72 } = \frac { 119 } { 72 } = 1 \frac { 47 } { 72 }

Add Then Write the Sum in Lowest Terms $\frac { 5 } { 8 } + \frac { 7 } { 12 } + \frac { 4 } { 9 }$
