Firstly you have to work out how long it would take one person to do the task. You know that 1 person would take longer to do something than say 4. So you multiply it.
More people will take less time to do something. So you divide the total of 1 persons work between them. Dont worry if it turns out as a decimal.
Hope I could help

Because multiplication and division are inverse operations. And the reciprocal of a number is its multiplicative inverse.
proportions are used in scale factors; scale factors ARE proportions

The original function's RANGE becomes the inverse function's domain.
It is a relationship of direct proportion if and only if the graph is a straight line which passes through the origin. It is an inverse proportional relationship if the graph is a rectangular hyperbola. A typical example of an inverse proportions is the relationship between speed and the time taken for a journey.

Low and high mass stars are indirectly related; high mass stars evolve faster and have shorter lifespans compared to low mass stars. This is because high mass stars burn through their fuel at a faster rate due to their higher core temperature and pressure.
These are the for inverse operations:Multiplications inverse is divisionDivisions inverse is multiplicationAdditions inverse is subtractionSubtractions inverse is addition
because if you compare it to 100% or 100 it will give you the correct answer to your problem.
