Answer 1

Explicație pas cu pas:

a)(32-16):8=16:8=2

(32-16):8=32:8-16:8=4-2=2

b)(57-33):3=24:3=8

(57-33):3=57:3-33:3=19-11=8

c)(48+56):4=104:4=26

(48+56):4=48:4+56:4=12+14=26

d)(98-26):2=72:2=36

(98-26):2=98:2-26:2=49-13=36

e)(50+28):2=78:2=39

(50+28):2=50:2+28:2=25+14=39

f)(99-36):9=63:9=7

(99-36):9=99:9-36:9=11-4=7

g)(84-64):4=20:4=5

(84-64):4=84:4-64:4=21-16=5

h)(72+84):6=156:6=26

(72+84):6=72:6+84:6=12+14=26

i)(65-55):5=10:5=2

(65-55):5=65:5-55:5=13-11=2

y)(72-36):2=36:2=18

(72-36):2=72:2-36:2=36-18=18
