Answer:
1 gallon = 3.8 liters rounded to the nearest tenth.
Explanation:
1 gallon = 3.785 litres.
We have to round this in to nearest tenths, nearest tenth means number of figures after decimal = 1.
Here last digit is 5 so we have to add 1 to previous digit.
So, 3.785 rounded will become 3.79
For 3.79 the last digit is 9 so we have to add 1 to previous digit.
So, 3.79 rounded will become 3.8
3.785 liters rounded to the nearest tenth is 3.8 liters.
1 gallon = 3.8 liters rounded to the nearest tenth.
