tita membeli 2,5m pita membeli lagi 1 3/4m kemudian 3/4m dipakai untuk mengikat rambutnya sisa pita tita skrng adalah… m
2,5 + 1 3/4 - 3/4 = 25/10 + 7/4 - 3/4
= 5/2 + 7/4 - 3/4
= 10/4 + 7/4 - 3/4
= 17/4 - 3/4
= 14/4 m
N = 2,5 + 1 3/4 – 3/4
n = 25/10 + (1 3/4 – 3/4 )
n = 25/10 + 3/4
n = kpk 4 dan 10 = 20
25×2/20 + 3×5/4
50/20 + 15/20
45/20 = 2 5/20 m atau 2,25
