174 x 36 - 174 x 26 

2/3 x 4/5 +1/8 x 2/3

Answer 1

174 x 36 - 174 x 26
= 174 x ( 36 - 26 )
= 174 x 10
= 1740

2/3 x 4/5 + 1/8 x 2/3
= 2/3 x ( 4/5 + 1/8 )
= 2/3 x 37/40
= 37/60

Answer 2

`=174xx(36-26)`

`=174xx10=1740`

`=2/3xx(4/5+1/8)`

`=2/3xx37/40=37/60`

Answer 3

174 x ( 36-26) = 1740

\(\dfrac{2}{3}x\left(\dfrac{4}{5}+\dfrac{1}{8}\right)=\dfrac{2}{3}x\dfrac{37}{40}=\dfrac{37}{60}\)

Answer 4

174 x 36 - 174 x 26 

= 174 x ( 36 - 26 )

= 174 x 10

= 1740

2/3 x 4/5 +1/8 x 2/3

= 2/3 x ( 4/5 +1/8 )  

= 2/3 x 37/40

= 37/60

Answer 5

174 x 36 - 174 x 26
= 174 x ( 36 - 26 )
= 174 x 10
= 1740
2/3 x 4/5 + 1/8 x 2/3
= 2/3 x ( 4/5 + 1/8 )
= 2/3 x 37/40
= 37/60
