Thank you
so we look at the 6th digit and see what happens which happens to be an 8 right so then we increase the number of the next digit to the left by 1 and so on until you reach simply a number which isn't a 9, so that 8 there increases to 9 from the 9 to the right of it
so we get 0.99900

5. You start from the first number that isn't 0, count five numbers and round. so this would be 0.99900. Go onto youtube and watch the channel hegartymaths 's video about it. hope this helped

Sorry, I have misread the question. Thought it read to 2 significant figs, when its not . 0.99900 is correct
