Anya Trevino · Answer 1

1/20 =.05

so each sheet is. 05 of a cm.

50*.05 = 2.5

by multiplying 50 (the number of sheet) by. 05 (the height of one card) you get 2.5 the height of 50 cards.

Wade Mora · Answer 2

20 / 1 = 50 / x ... 20 sheets to 1 cm = 50 sheets to x cm

cross multiply

(20) (x) = (1) (50)

20x = 50

x = 50/20

x = 5/2 = 2 1/2 cm (or 2.5 cm) <==
