1)5 1/2×30% 2),2/3×2,5÷50%+1 1/6= 3)36/5÷45%= 4)1/5×3 6/9= 5)7/4÷8/6= no asal!!

1) 5 1/2 × 30/100 = 11/2 × 3/10 = 33/20 = 1 13/20

2) 2/3 × 25/10 : 5/10 + 7/6 = 10/3 + 7/6 = 20/6 + 7/6 = 27/6 = 4 3/6 = 4 1/2

3) 36/5 : 45/100 = 36/5 × 100/45 = 16

4) 7/4 × 6/8 = 1 11/16

Berikut ini adalah jawaban nomor 1 s.d.5.
Semoga membantu.
1)5 1/2 × 30%=11/2 × 3/10=33/20=1 13/20.
2)(2/3 × 2,5 ÷ 50%)+ 1 1/6=(2/3 × 5/2 ÷ 1/2) + 7/6
=(2/3 × 5/2 × 2/1) + 7/6
=20/6 + 7/6
=27/6=4 3/6=4 1/2.
3.36/5 ÷ 45%=36/5 ÷ 9/20=36/5 × 20/9
=720/45=16.
4.1/5 × 3 6/9=1/5 × 33/9=33/45=11/15.
5.7/4 ÷ 8/6=7/4 × 6/8=42/32=1 10/32=1 5/16.
