    However, you may sometimes be asked to round answers to the nearest integer.

  • True or False?

    Large monetary amounts, such as the cost of a car, are usually rounded to the nearest whole number, e.g. nearest dollar.

  • True or False?

    Exchange rates can be written as ratios.

    True.

    Exchange rates can be written as ratios.

    E.g. table row blank blank cell GBP space open parentheses £ close parentheses space colon space USD space open parentheses $ close parentheses space end cell row blank blank cell space space space space space space space space space space space space space space 1 space colon space 1.27 end cell end table

  • How do you use an exchange rate £1 = $1.25 to convert £ into $?

    Given an exchange rate of £1 = $1.25, you can convert £ into $ by multiplying your value in £ by 1.25.

    E.g. Convert £16 into $.
    16 × 1.25 = $20.

  • True or False?

    An exchange rate is given as £1 = $1.25.

    To convert $10 into £ you perform the calculation 10 divided by 1.25.

    True.

    If £1 = $1.25 then to convert $10 into £ you work out 10÷1.25.
