Answer:
45cm
Step-by-step explanation:
Add 4+3+5 which is 12. Divide 180 by 12 which is 15. Now multiply 15 to each number (4x15, 3x15, and 5x15) The smallest would be 3x15=45
Check
4x15=60
3x15=45
5x15=75
60+45+75=180
Answer:
The height of the smallest sister is 45 cm
Step-by-step explanation:
We are given that the heights of the three sisters are in the ratio 4:3:5
Let the ratio be x
So, The heights of three sisters are 4x,3x and 5x
We are given that The total height of three of Thumbelina’s sisters is 180 cm.
So, [tex]4x+3x+5x=180[/tex]
[tex]12x=180[/tex]
[tex]x=\frac{180}{12}[/tex]
[tex]x=15[/tex]
Height of smallest sister = 3x=3(15)=45 cm
Hence The height of the smallest sister is 45 cm
