Question

Sally is 148cm tall. The ratio of Sally to the height of the apple tree in her garden is 1:2. How tall in meters is the apple tree?

Answer 1

so the height of apple tree in meters is 3 meters

Explanation:

by using ratio and proportion rule

1:2=148:x

`(1)/(2)=(148)/(x)`

by cross multiplication

1×x=2×148

1x=296cm

converting into meter as we know that 1centi=10^-2

1x=296×10^-2

x=2.96m≈3meters
