x= 100 x=48

(1) Total pages of this book *( 1- 3/5) = remaining pages.

X*( 1- 3/5) =36？ x = 90°

(2) Number of red chalk boxes *( 1+ 2/3) = Number of white chalk boxes.

X*( 1+ two thirds) = 100 x=60.

(25+35) divided by 15/3 1 = 124 (ten thousand units)

The first method: solution: set X sheep.

X*( 1+ one ninth) =30? x=27

The second method: 30 divided by (1+ one ninth) =27.

4400 divided by (1- 9/20) =8000 (m)

54 65438+46 out of 035? 35 ? 135 divided by 360= three eighths.

12000 divided by (1-1/4) =16000 (m)

16000 divided by (1- 5) =20000 (m)
