12. 2 1/2 - 0,8 + 3/4
= 5/2 - 8/10 + 3/4
= 50/20 - 16/20 + 15/20
= 49/20
= 2 9/20
13. 2 1/2 ÷ 1,2 × 3/4
= 5/2 ÷ 12/10 × 3/4
= 5/2 × 10/12 × 3/4
= 150/96
= 1 54/96
= 1 9/16
14. 3,75 - 2 1/2 + 1,5
= 3,75 - 2,5 + 1,5
= 2,75 liter
bentuk pecah nya 2 3/4 liter
15. 2/5 × 10000 = Rp 4.000,00 (yg ditabung)
yg tdk ditabung 10000-4000 = Rp 6.000,00
