Question

A dollhouse uses the scale 1:10. A chair in the dollhouse is 8 centimeters tall.

How tall is the actual chair?

8 m
0.08 m
0.8 m
80 m

Answer 1

let h = height of the chair

So if the scale is 1:10 and the chair in the dollhouse is 8 cm, then


1/10 = 8/h


Solve this for h and tell me what you get

Answer 2

do you solve h by dividing1/10

Answer 3

do i set up a proportion

Answer 4

you can, but i find it easier to cross multiply

1/10 = 8/h

1*h = 10*8

h = 80

Since h is in cm, this means

80 cm = 0.8 m

Answer 5

o

Answer 6

since

(80 cm)*(1 m/100 cm) = 80/100 = 0.8 m

Answer 7
