nomor 5
= 0,75 + 2/5 : (5/8 - 0,25) x 1 1/8
= 3/4 + 2/5 : (5/8 - 1/4) x 9/8
= 3/4 + 2/5 : (5/8 -2/8) x 9/8
= 3/4 + 2/5 : 3/8 x 9/8
= 3/4 + 2/5 x 8/3 x 9/8
= 3/4 + 16/15 x 9/8
= 3/4 + 144/120
= 90/120 + 144/120
= 234/120
= 1 114/120
= 1 57/120
nomor 6
= 5 (5 3/4) - 12 5/8
= 5 (23/4) - 12 5/8
= 115/4 - 12 5/8
= 28 3/4 - 12 5/8
= 28 6/8 - 12 5/8
= 16 1/8
jadi, sisa tali yang masih tersisa adalah 16 1/8 m
