Penjelasan dengan langkah-langkah:

1. 3/8, 2/5, 1/7, 3/4 = 0,375, 0,4, 0,142, 0,75

Terbesar = 3/4, 2/5, 3/8, 1/7

2. 18/45 = 6/15 = 2/5

3. 8/12 = 4/6 = 2/3

4. 50 x 12/100 = 600/100 = 6

5. x/18 = 5/6

6x = 90

x = 90 : 6 = 15

6. 1,25 – 1/5 x 1,25

125/100 – 1/5 x 125/100

125/100 – 125/500

5/4 – 1/4 = 4/4 = 1

7. 3/5 x 50 menit = 30 menit x 60 = 1800 detik

8. 1,30 x 100 = 130%
