- 1.Which of these is written correctly in standard form?
- 2.Light travels at 2.998 × 10⁸ metres per second. A distant object in space is 3.1 × 10¹⁵ metres from Earth. Work out an estimate for the number of seconds light takes to travel from the object to Earth, by rounding each number to 1 significant figure.
- 3.A cycle route is 350 m long. A footpath runs alongside it for 3/7 of that length. Work out the length of the footpath.
- 4.Two lighthouses flash at the start of the same minute. The first lighthouse flashes every 8 minutes and the second flashes every 12 minutes. Work out how many minutes it will be until they next flash together.
- 5.A number, y, is equal to 8.2 when rounded to 1 decimal place. Write down the error interval for y.
- 6.A number, x, is truncated (not rounded) to 1 decimal place and the result is 6.2. Write down the error interval for x.
