The expressions that represent the amount of olive oil needed for 4 tablespoons of lemon juice is 2J
How to form mathematical expression from the given description?
You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
We're given that:
- Olive oil is twice as much as lemon juice
- There is 'J' number of tablespoons of lemon juice.
Twice means doing double, for which we can add the amount twice, or multiply it by 2.
Thus, we get:
Amount of olive oil needed = J + J tablespoon = 2×J tablespoon of olive oil
Thus, the expressions that represent the amount of olive oil needed for 4 tablespoons of lemon juice is 2J
