Explicación paso a paso:
1.
a. (–15)(2)–(–16)/(–8)
(–30)–2=–32
b. (–12)+(–9)(6)/(–2)
–12+(–54)/(–2) = –12+27 = 15
c. 7–3(–4)–27/(–9)
7–(–12)–(–3) = 7+12+3 = 22
d. (–45)–(–49)/7(–6)
–45–(–7)(–6) = –45–(+42) = –45–42 = –87
e. (-20)+6(–5)/(–2)
–20+(–30)/(–2) = –20+15 = –5
2.
a. (3–8)+[5–(–2)]
–5+[5+2] = –5+7 = 2
b. 5–[63–2–(12–8)–3+6]
5–[61–(4)–9] = 5–[57–9] = 5–48 = –43
c. 18/[12/(–2)]
18/(–6) = –3
d. (5+3(2)/6–4)(4/2–3+6)
(5+6/6–4)(2–9) = (5+1–4)(–7) = (2)(–7) = –14
3.
a. 15+18/3 = (15+18)/3
15+6 = 33/3
21 = 11
No es cierta está igualdad
b. 96/[(4–2)(6)]=96/4–2(6)
96/[(2)(6)]=24–12
96/12=12
8=12
No es igualdad
c. 7–(12–9)=7–12+9
7–(3)=–5+9
4=4
Está igual es cierta
d. 29+[35/(–5)]=29+35/(–5)
29+[–7]=29+(–7)
22=22
Está igualdad es cierta
