1. 180.000,00 × 40/100 = 72.000,00
180.000,00 + 72.000,00 = 252.000,00

2. 4/5 × 8/10 ÷ 1/2 = 32/50 × 2 = 32/25 = 1 7/25

3. anggap x = uang Sinta seluruhnya
3/4 × x = 12.000,00
x = 12.000,00 × 4/3
x = 16.000,00

4. 1 - 1/3 - 1/2 = 6/6 - 2/6 - 3/6 = 1/6

5. 3/4 + 1/2 + 1/2 + 1/3 = 9/12 + 6/12 + 6/12 + 4/12 = 25/12 = 2 1/12 kuintal
