b) 91.25 - 91.13 - 91.12

c) 25.36 - 25.32 + 25

d)121.74 + 74.45 - 66.74

e) 136.23 + 27.136 - 136.40

Answer 1

a 5,508,550
b 339,612
C28,025
d 30,058,356
e17,157,760

Answer 2

\(a,58\times75+58\times50-58\times25=58\times\left(75+50-25\right)=58\times100=5800\)

\(b,91\times25-91\times13-91\times12=91\times\left(25-13-12\right)=91\times0=0\)

\(c,25\times36-25\times32+25=25\times\left(36-32+1\right)=25\times5=125\)

\(d,121\times74+74\times45-66\times74=74\times\left(121+45-66\right)=74\times100=7400\)\(e,136\times23+27\times136-136\times40=136\times\left(23+27-40\right)=136\times10=1360\)

Answer 3

a, =58.(75+50-25)=58.100=5800

b, =91.(25-13-12)=91.0=0

c, =25.(36-32+1)=25.3=75

d, =74.(121+45-66)=74.100=7400

e, =136.(23+27-40)=136.10=1360

Answer 4

\(a)=\left(58,75+58,25\right)-58,50\)

     \(=117-58,50\)

     \(=58,5\)
