1. 2,5+40/50= 2. 1 9/10 + 2% = 3. 2 2/5 +10% = 4. 1 9/25 + 3%= 5. 4 1/4 + 15% = 6. 2 7/10 + 25% = Tolong jawabnya pakai cara

1. 2,5 + 40/50
= 25/10 + 40/50
= 250 + 80/100
= 330/100.

2. 1 9/10 + 2%
= 19/10 + 2/100
= 190 + 2/100
= 192/100

3. 2 2/5 + 10%
= 12/5 + 10/100
= 240 + 10/100
= 250/100

4. 1 9/25 + 3%
= 34/25 + 3/100
= 136 + 3/100
= 139/100

5. 4 1/4 + 15%
= 17/4 + 15/100
= 425 + 15/100
= 440/100

6. 2 7/10 + 25%
= 27/10 + 25/100
= 270 + 25/100
= 295/100

Semoga membantu!!!
