Evaluate fraction x fraction

  1. Apr 22, 2010 #1
    What does the word mean when you are presented with a question like this?

    Evaluate 3 1/3 x 1 1/5

    Is it simply asking us to work out the answer to the sum?

    A sum? Isn't this a product of fractions? In words, three wholes and one third times one whole and one fifth?

    As Radou noted, this is a product, not a sum. The two numbers are mixed numbers (a whole number plus a fraction), which are not very useful for calculations. Convert each of the mixed numbers to an improper fraction, and then multiply, using the rules of fraction multiplication.

    Hi Mark
    Thanks once again fior helping out.
    Does that mean the solution is as follows?
    10/3 x 6/5 = 60/15 = 4
    When the question says, "Evaluate", I guess it just means "work out the answer"?

    Yes, "evaluate" simply means "do the arithmetic".

    And, radou and Mark44, "sum" is a common Britishism for any arithmetic problem.
