bought 1 5/8 kg of ham, 6 1/4 kg of sliced corned beef and 5/8 kg of coleslaw =total weight?
ham =1 5/8kg = 1+ 5/8 = (1 *8 + 5)/8 { after doing LCM }
= (8 +5) /8
ham = 13/8 kg------------------(1)
beef =6 1/4 = 6 + 1/4 = ( 6*4 + 1 )/4
= (24 + 1 )/4
beef = 25 / 4kg--------------------------------(2)
cole slaw = 5/8 kg -----------------------------------(3)
Total = (1) + (2) + (3)
= 13/8 + 25/ 4 + 5/8
= 13/8 + (25 *2)/ (4* 2) + 5/8 [ making all denominaters equal
we did 25/2 = (25 *2)/(4*2) ]
= 13/8 + 50/8 + 5/8
= (13 + 50 + 5)/8
= (68) / 8
= 17/2
= 8.5kg
