Answer 1

a,

58.75 + 58.50 - 58.25

= 58.(75 + 50 - 25)

= 58. (125 - 25)

= 58.100

 = 5800

Answer 2

b, 27.39 + 27.63 - 2.27

= 27.(39 + 63 - 2)

= 27.(102 - 2)

= 27.100

= 2700 

Answer 3

c, 128.46 + 128.32 + 128.22

= 128.(46 + 32 + 22)

= 128.(78 + 22)

= 128.100

= 12800

Answer 4

d, 12.35 + 35.182 - 35.94

= 35.(12 + 182 - 94)

= 35.(194 - 94)

= 35.100

= 3500

Answer 5

e, 48.19 + 48.115 + 134.52

= 48.19 + 48.115 + 134.52

= 48.(19 + 115) + 134.52

= 48.134 + 134.52

= 134.(48 + 52)

= 134.100

= 13400

Answer 6

f, 136.23 + 136.17 - 40.36

= 136.(23 + 17) - 40.36 

= 136.40 - 40. 36

= 40.(136 - 36)

= 40.100

= 4000

Answer 7

g, 17.93 + 116.83 + 17.23

= 17.(93 + 23) + 116.83

= 17.116 + 116.83

= 116.(17 + 83)

= 17.100

= 1700

Answer 8

h, 19.27 + 47.81 + 19.20

= (19.27 + 19.20) + 47.81

= 19.(27 + 20) + 47.81

= 19.47 + 47.81

= 47.( 19 + 81)

= 47.100

= 4700

Answer 9

I, 87.23 + 13.93 + 70.87

= (87.23 + 70.87) + 13.93

= 87.(23 + 70) + 13.93

= 87.93 + 13.93

 = 13.(87 + 13)

= 13.100

= 1300
