Question

(X – 12,7) : 0,48 = 427 ,5                                     20,49 + x = 7,25 x 6,28

Answer 1

`(x - 12,7) : 0,48 = 427,5`

`x - 12,7 = 427,5 xx 0,48`

`x - 12,7 = 205,2`

`x = 205,2 + 12,7`

`x =  217,9`

_________________________

`20,49 +x = 7,25 xx 6,28`

`20,49 +x  = 45,53`

`x = 45,53 - 20,49`

`x =25,04`

Answer 2

(X – 12,7) : 0,48 = 427 ,5

(X – 12,7) = 427,5 \(\times\) 0,48

(X – 12,7) = 205,2

X = 205,2 + 12,7

X = 217,9

20,49 + x = 7,25 x 6,28

20,49 + x = 45,53

x = 45,53 - 20,49

x = 25,04.

Answer 3

\((x – 12,7) : 0,48 = 427 ,5 \)

\(x – 12,7 = 427 ,5 . 0,48\)

\(x – 12,7 = 205,2\)

\(x = 205,2+ 12,7\)

\(x=217,9\)

\(-----------\)

\( 20,49 + x = 7,25 x 6,28\)

\( 20,49 + x = 45,53\)

\( x = 45,53 - 20,49 =25,04\)

Answer 4

(X - 12,7) : 0,48 = 427,5

(X - 12,7)           = 427,5 x 0,48

X - 12,7              = 205,2

         X               = 205,2 + 12,7

         X               = 217,9

Vậy X = 217,9

20,49 + X = 7,25 x 6,28

20,49 + X = 45,216

             X = 45,216 - 20,49

             X = 24,726

Vậy X = 24,726
