hasil dari bilangan campuran 2 1/2:1 2/3+5 3/4-1 1/4x1 1/3= dengan caranya ya

= (2 1/2 : 1 2/3) + 5 3/4 - (1 1/4 × 1 1/3)
= (5/2 : 5/3) + 23/4 - (5/4 × 4/3).
= (5/2 × 3/5) + 23/4 - 20/12.
= 15/10 + 23/4 - 20/12.
= 90/60 + 345/60 - 100/60.
= 335/60.
= 5 35/60.
= 5 7/12.

2 1/2:1 2/3+5 3/4-1 1/4×1 1/3
=5/2:5/3+23/4-5/4×4/3
=(5/2×3/5)+23/4-5/4×4/3
=3/2+23/4-(5/4×4/3)
=(3/2+23/4)-20/12
=(6/4+23/4)-20/12
=29/4-20/12
=87/12-20/12
=67/12=5 7/12
