Answer 2

question ;

Pinky had 3 ¼ metre of red ribbon. She 2 ½ used metre of ribbon to wrap gifts. How much ribbon is left with her ?

answer ;

• meter of ribbon pinky had : 3 ¼
• meter of ribbon used to wraped in gifts : 2 ½

• step 1 : covert this into a proper fraction ;
• 13/4 , 5/2

• step 2 : now take Lcm from the denominator ( picture )
• so Lcm = 4

• 
  `(13 *1 )/(4 * 1) = (13)/(4)`

• 
  `(5 * 2)/(2 * 2) = (10)/(4)`

• now add them ;
• 13/4 + 10/4 = 23/4

• 3/4 is your answer
