4 1/2 - 2 6/12 ÷ (2 1/2 + 1 1/4) tolong dibantu cari jawabannya + caranya ya kak soalnya besok dikumpul

4 1/2 - 2 6/12 : ( 2 1/2 + 11/4 )
= 9/2 - 30/12 : ( 5/2 + 11/4 )
= 9/2 - 30/12 : 21/4
= 9/2 - ( 30/12 : 21/4 )
= 9/2 - ( 12/30 × 21/4 )
= 9/2 - 21/10
= 24/10
= 2 4/10 ( pecahan campuran)
= 2,4 ( desimal)

Smoga membantu :) ^ ^
