3) Rita has 3/4 m of Ifugao cloth. She used 2/3 m for placement. What part

enot [183]

Answer:

$Unused = \frac{1}{12}m$

Step-by-step explanation:

Given

$Total= \frac{3}{4}m$

$Used= \frac{2}{3}m$

Required

Determine the part left

The part left is calculated using:

$Used + Unused = Total$

$Unused = Total - Used$

$Unused = \frac{3}{4}m - \frac{2}{3}m$

Take LCM

$Unused = \frac{9m - 8m}{12}$

$Unused = \frac{1m}{12}$

$Unused = \frac{1}{12}m$
