1) 1 2/3 + 2/8 : 1/2 =
5/3 + 2/8 : 1/2 =
5/3 + 2/8 × 2/1 =
5/3 + 4/8 =
40/24 + 12/24 =
52/24 = 2 4/24 =
2 1/6

2) 30% : 2/5 × 2/3 =
30/100 : 2/5 × 2/3 =
30/100 × 5/2 × 2/3 =
150/200 × 2/3 =
300/600 = 1/2

3) 0,15 × 1/3 : 10% =
15/100 × 1/3 : 10/100 =
15/300 × 100/10 = 1.500/3.000 = 1/2

4) 1 2/5 : 0,5 + 30% =
7/5 : 5/10 + 30/100 =
7/5 × 10/5 + 30/100 =

310/100 = 3 10/100 = 3 1/10

Smoga membantu :))

1. 1 2/3 + 2/8 ÷ 1/2
=> 5/2 + 2/8 ÷ 1/2
=> 5/2 + ( 2/8 x 2/1)
=> 5/2 + 4/8
=> Samakan Penyebutnya.
20/8 + 4/8= 24/8 = 3.

2. 30% ÷ 2/5 x 2/3
=> 30/100 x 5/2 x 2/3
=> 300/600
=> 1/2

3. 0,15 x 1/3 ÷ 10%
=> 15/100 x 1/3 ÷ 10/100
=> 15/100 x 1/3 x 100/10
=> 1.500/3.000
=> 1/2

4. 1 2/5 ÷ 0,5 + 30%
=> 7/5 ÷ 5/10 + 30/100
=> (7/5 x 10/5) + 30/100
=> 70/25 + 30/100
=> Samakan penyebutnya.
280/100 + 30/100
=> 310/100 = 3 10/100

Semoga dapat membantu anda semua.
