Problem Solving With Rational Numbers in Fraction Form
18. One ninth of the height of an iceberg was above the surface of the water. The iceberg extended to a depth of 75.8 m below the surface. What was the height of the iceberg above the surface? Express your answer to the nearest tenth of a meter.
Here's how I solved this question.
First, since we need to find out what one ninth of the iceberg is then the 75.8 would be the rest of the whole which is eight ninths.
You can get 1/9 if you divide 8/9 by 8 so when I divided 75.8 by 8 I got 9.475 but when you simplify it, it would be 9.5m.
The height of the iceberg above the surface is 9.5m.
