jadikan pecahan campuran atau sederhanakan soal: 1. (40% + 1/2)×250 2. 4/5 : 3/2 - 1/3 tolong bantu dan pake cara plese

1. 40/100 + 1/2 x 250 = (2/5 + 1/2 ) x 250 = ( 4/10 + 5/10 ) x 250 = 9/10 x 250 = 9 x 25= 225

2. 4/5 : 3/2 - 1/3 = (4/5 x 2/3) - 1/3 = 8/15 - 1/3 = 8/15 - 5/15 = 3/15

1. (40% + 1/2) X 250
= (40/100 + 1/2) × 250
= (40/100 + 50/100) × 250
= (90/100) × 250
= 9/10 × 25
= 22.5

2. 4/5 : 3/2 - 1/3
= 4/5 × 2/3 - 1/3
= 8/15 - 1/3
= 8/15 - 5-15
= 3/15
= 1/5
