Penjelasan dengan langkah-langkah:

1.    3/4+2/3 = 17/12= 1 5/12(b)

2.    3 1/4 - 1 7/12 = 3-1 (12-28/48)= 2 16/48=2 1/3(c)

3.    15% x 1 1/3 = 15/100 x 4/3 =60/300 = 20/100 = 1/5(a)

4.    2 1/4 : 5/12 = 9/4 x 12/ 5 = 108/ 20 = 5 8/20= 5 2/5(a)

5perbandingan = 7/4 = 7+4= 11

pedangan a = 7/11x55.000=35.000

pedagang b= 4/11x 55.000=20.000

35-20=15.000(d)

skala = jarak pada peta ; jarak asli

s= 3cm; 5km= 3cm:1.500.000= 500.000

skala = 1:500.000(c)

bang kasih jawaban tercerdas lah bang

Answer 2

Verified answer

1. 3/4 + 2/3 = 3 (3) + 2(4)/12

= 9+8/12 = 17/12 = 1 5/12 (B)

2. 13/4 - 19/12= 13(3)-(19)(1)/12

= 39-19/12 = 20/12 = 10/6 = 5/3 = 1 2/3 (B)

3. 15/100 x 4/3 = 5/25 = 1/5 (A)

4. 9/5 : 5/12= 9/4x12/5

= 27/5 = 5 2/5

5. pedagang A = 7/11x55000= 35000

pedagang B = 4/11x55000= 20000

selisih pedagang A dan B adalah 15000 (D)

6. skala= jarak pada peta/jarak sebenarnya

= 3/15000000 = 1/500000 = 1: 500000 (C)
