Answer 1

a,=235.(64+36)=235.100=23500

b,=376.(236-136)=376.100=37600

c,=459.(99+1)=459.100=45900

d,=567.(125-25)=567.100=56700

Answer 2

\(=235\times\left(64+36\right)=235\times100=23500\)

\(=376\times\left(236-136\right)=376\times100=37600\)

\(=459\times\left(99+1\right)=459\times100=45900\)

\(=567\times\left(125-25\right)=567\times100=56700\)

Answer 3

`235 xx 64 + 235 xx 36`

`= 235 xx 100`

`= 23500`

________________

`376 xx 236 - 136 -136 xx 376`

`= 376 xx (236 - 136)`

`= 376 xx 100`

`= 37600`

_________________

`459 xx 99 + 459 xx 1`

`= 459 xx (99 + 1)`

`= 459 xx 100`

`= 45900`

________________

`567 xx 125 - 25 xx 167`

`= 567 xx (125 - 25)`

`= 567 xx 100`

`= 56700`

Answer 4

235 x 64 +235 x 36 = 235 x ( 64 + 36 ) = 235 x 100 = 23500.
376 x 236 - 136 x 376 = 376 x ( 236 - 136 ) = 376 x 100 = 37600.

459 x 99 + 459 = ( 459 x 99 ) + 459 = 45441 + 459 = 45900.
567 x 125 - 25 x 567 = 567 x ( 125 - 25 ) 567 x 100 = 56700.
