Answer:
1.65 metres
Explanation:
Previously, the height was 1.5 metres. Then the plant grew 15 centimetres. Unfortunately, we cannot just add 15 to 1.5 because metres and centimetres are different. We must convert centimetres into metres.
There are 100 cm in 1 m, so let's set up a proportion:
, where x is the number of metres in 15 cm
Cross-multiply:
100 * x = 15 * 1
100x = 15
x = 0.15 metres
Now, add 0.15 to 1.5:
1.5 + 0.15 = 1.65 metres
Hope this helps!
