a,

\(\frac{326}{325}-\frac{1}{325}=1\)                        \(\frac{325}{324}-\frac{1}{324}=1\)

Vì \(\frac{1}{325}< \frac{1}{324}\)nên \(\frac{326}{325}< \frac{325}{324}\)

b,

( 11 x 9 - 900 x 0,1 - 8 ) x ( 56,7 x 0,5 + 56,7 x 9,5 )

= ( 99 - 90 - 8 ) x [ 56,7 x ( 0,5 + 9,5 ) ]

= ( 9 - 8 ) x ( 56,7 x 10 ) 

= 1 x 567 = 567

a) 36  ÷ 0,1 = 360  ;  36  ÷ 10 = 3,6

b) 140  ÷ 0,1 = 1400  ;  140  ÷ 10 = 14

c) 325  ÷ 0,01 = 32500  ; 325  ÷ 100 = 3,25

a, 36 : 0,1 = 360

36 : 10 = 3,6         

b, 140 : 0,1 = 1400

140 : 10 = 14

c, 325 : 0,01 = 32500

325 : 100 = 3,25

y + 576 × 11 - 325 = 45897

y + 6336 = 45897 + 325

y + 6336 = 46222

=> y = 46222 - 6336

=> y = 39886

Vậy y = 39886

y + 576 x 11 - 325 = 45897

y + 6336 - 325 = 45897

y + 6011 = 45897

y = 45897 - 6011

y = 39886

Vậy y = 39886

Nhớ k cho mình nhé! Thank you!!!

y + 576 x 11 - 325=45897

y + 576 x 11 =45897+325

y + 576 x 11 =46222

y + 576=46222:11

y+ 576=4202

y=4202-576

y=3626

a) ( x : 273 ) - 946 = 754

x : 273 = 754 + 946

x : 273 = 1700

      x    = 1700 x 273

      x    = 464100

b) ( 325 - x ) : 11 = 18

325 - x = 18 x 11

325 - x = 198

        x  = 325 - 198

       x   = 127

1)  x=464100

2) x=127

(X:273)-946=754

=>X:273=754+946

=>X:273=1700

=>X=1700x273

=>X=464100

(325-X):11=18

=>325-X=18x11

=>325-X=198

=>X=325-198

=>X=127

420: x + 27 . 11= 325

420:x+297=325

420:x=28

x=420:28

x=15

Vậy x=15

420: x+ 27. 11= 325

=> 420: x+ 297= 325

=> 420: x= 325- 297

=> 420: x= 28

=> x= 420: 28

=> x= 15

Vậy x= 15

\(420:x+27\cdot11=325\)

\(420:x+297=325\)

\(420:x=325-297\)

\(420:x=28\)

\(x=420:28\)

\(x=15\)

Vậy \(x=15\)
