Kk tolong bantu jawab yak…. Plisssssss….

Jawaban:

4. 8-7-(6-11)+((-5)+(-1))

= 8-7-(-5)+(-6)

= 1-(-5)+(-6)

= 6+(-6)

= 0 (c)

Jawaban:

3. 4/7 = 0,58 ; 6/8 = 0,75 ; 2/3 = 0,67 ; 3/5 = 0,6

Jadi, urutan dari yg terkecil adalah :

4/7 ; 3/5 ; 2/3 ; 6/8 (b)

4. 8–7–(6–(6+5))+((-5)+(–4+3))

= 8–7–(–5)+(-6)

= 8–7+5–6

= 0 (c)

5. 3/4 + 7/12 : (–2/3)

= 3/4 + 7/12 x (–3/2)

= 3/4 + (–21/24)

= 3/4 – 21/24

= 3/4 – 7/8

= 6–7/8

= –1/8 (a)
