Selesaikan soal berikut sesuai urutan pengerjaan yang benar a. 1,25 - 0,5 × 1/5 = b. 1/4 + 1,5 : 0,25 = c. 2 4/5 × 1/8 - 0,15 =

a.1.25-0.5 x 1/5
= 1.25-0.5 x 0.2
=1.25-0.1
=1.15

b.1/4+1.5÷0.25
=0.25+1.5÷0.25
=0.25 + 6
=6.25

c. 2 4/5 x 1/8 - 0.15
=14/5 x 1/8 -0.15
=14/40-0.15
=0.35-0.15
=0.20
=0.2

d.35%+2 4/5 x (0.25+1/5)
=0.35 + 14/5 x (0.25+0.2)
=0.35+2.8 x 0.45
=0.35 +1.26
=1.61

e.2.5:1/4-1 1/5x20%
=2.5:0.25- 6/5x0.20
=10-1.2x0.20
=10-0.24
=9.76

f.3 5/6x0.4-1 1/8:3/4
=23/6 x 0.4 - 9/8:3/4
=23/6x2/5-9/8x4/3
=46/30-36/24 (disederhanakan)
=23/15-18/12 (disamakan penyebut ya)
=92/60-90/60
=2/60
=1/30
