JME function reference

Description

Some sets of units that you might reasonably convert between. A set of units is randomly picked, and then shuffled. The first item in the list is the "from" unit, and the second item is the "to" unit.

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `list`

[ "l", "cl", "ml" ]

→ Used by:

from_unit
to_unit

This variable doesn't seem to be used anywhere.

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Write $\var{from_amount}$ in {units_string(to_unit)}.

$\var{from_amount} =$ Unnamed gap

Advice

There are $\var{(from_unit/to_unit) * units(to_unit)}$ in $\var{units(from_unit)}$.

To convert $\var{from_amount}$ to {units_string(to_unit)}, multiply by {1/scale}:

\[ \var{abs(from_amount)} \times \var{1/scale} = \var{abs(to_amount)} \]

So $\var{from_amount} = \var{to_amount}$.

Give a worked solution to the whole question.
