Answer 1

3.

2 1/2 × 8

= 5/2÷2 × 8÷2/1

= 5/1 × 4/1

= 20/1

4.

2 4/5 ÷ 3

= 14/5 ÷ 3/1

= 14/5 × 1/3

= 14/15

5.

(-10 + 4) × (-5-4)

= -6 × (-9)

= 54

6.

7 3/4 - 2 1/3

= 31×3/4×3 - 7×4/3×4

= 93/12 - 28/12

= 65/12

7

kurang jelas soalnya

8.

17 1/2 ÷ 2 1/2

= 35/2 ÷ 5/2

= 35/2 × 2/5

= 70/10

= 7/1

9.

6 1/4 × 1 2/5

= 25÷5/4 × 7/5÷5

= 5/4 × 7/1

= 35/4

= 4 3/4

10.

0,25

= 25/100

Answer 2

Jawaban:

3. 2½ × 8

= 5/2 × 8/1

= 20/1

= 20

4. 2⅘ ÷ 3

= 14/5 ÷ 3/1

= 14/5 × 1/3

= 14/15

5. ( -10 + 4 ) × ( -5 - 4 )

= -6 × -9

= 54

6. 7¾ - 2⅓

= 31/4 - 7/3

= 93/12 - 28/12

= 65/12

= 5 ⁵/¹²

7. a: (47 - 27 + 4)

b: (25 - 15 + 10)

= a, b

maka

47, 25 - 27, 15 + 4, 10

= 24, 2

8. (Maaf, pertanyaannya tidak begitu jelas, maka saya akan menggunakan semua operasi +, -, × dan ÷, tinggal dipilih saja ya)

(+) 17½ + 2½

= 35/2 + 5/2 = 40/2

= 20

(-) 17½ - 2½

= 35/2 - 5/2

= 30/2

= 15

(×) 17½ × 2½

= 35/2 × 5/2

= 175/4

= 43¾

(÷) 17½ ÷ 2½

= 35/2 ÷ 5/2

= 35/2 × 2/5

= 14/2

= 7

9. 6¼ × 1⅖

= 25/4 × 7/5

= 35/4

= 8¾

10. Pecahan Biasa Dari 0.62

= 62/100

= Disederhanakan: 31/50

Good luck :-)
