1)
0,475 = 475/1.000 = (475:25)/(1.000:25) = 19/40
2)
75% x 4.500 = 3x4.500/4 = 13.500/4 = 3.375
3)
Putra = (40-24)/40 x 100% = 1.600/40 % = 40%

4)
36/48 = 3/n
n = 48x3/36 = 48/12 = 4

5)
Lp = 2 x 5² + 4x5x12 = 50 + 240 = 290 cm²

Answer 2

1). 475/1000 = 19/40

2). 75/100 × 4500 = 3375

3). 40-24 = 16 ---▶ 16/100 × 100% = 40%

4). 36/48 = 3/4 ---▶ n = 4

5). 3,2 × 0,8 : 0,4 = 2,56 : 0,4 = 6,4
