tolong dibantu kak bagi yg gak tahu jangan dijawab ya

1) 3+7x5-15:5 = 3 + 35 - 3 = 35
2) 125 x 5 (75:25) - 1.500 : 15 = 125 x 5 (3) - 100 = 125x15-100 = 1.775
3) 7,5 + 0,5 x 1,75 - 0,65 = 7,5 + 0,875 - 0,65 = 7,725
4) 2/3 + 9/4 - 3/8 = 16/24 + 54/24 - 9/24 = 61/24 = 2 13/24
5) 6/24 x 6/4 = 36/96 = 6/16
