pls repede!​

Answer 1

a) 1375 + 96 - 100 + 849 =

= 1471 - 100 + 849 =

= 1371 + 849 =

= 2220

b) 55 : 5 x 3 x 2 : 2 = 11 x 3 x 2 : 2 = 33 x 2 : 2 = 66 : 2 = 33

c) 80 : 2 + (50 x 2 : 10 + 90) + 10 - 25 x 4 =

= 40 + (100 : 10 + 90) + 10 - 100 =

= 40 + (10 + 90) + 10 - 100 =

= 40 + 100 + 10 - 100 =

= 140 + 10 - 100 =

= 150 - 100

= 50
