1/2kali 3/5-5persen +1,25

1/2 × 3/5 - 5% + 1,25 = ( 1/2 × 3/5 ) - 5/100 + 125/100 = 3/10 - 5/100 + 125/100 = 30/100 - 5/100 + 125/100 = 150/100 = 15/10 = 3/2 = 1 1/2

(1/2 x 3/5) - 5% + 1,25
= 3/10 - 5/100 + 1,25
= 30/100 - 5/100 + 1,25
= 25/100 + 1,25
= 0,25 + 1,25 = 1,5 atau 1 1/2

Semoga membantu
