I'm not sure but...
First 1/3 one has 1 broken and 2 not broken bulb.
so if you break one more, 1/3 + 1/3 = 2/3 broken light bulbs, something like that?

Thank you so much for you input much appreciated.

I don't think it's you being silly.

At first glance I would say you had to draw each set of light bulbs from the previous question again, but change the number of light bulbs that are broken. Then write a new fraction to show the picture you have drawn. So you draw the string of 3 light bulbs, but with 2 broken bulbs not 3 so the fraction becomes 2/3 .

I don't get the 'do this 5 times' bit though. There are 6 strings so drawing 5 of them contradicts the 'draw each set' instruction. but you can't draw all of the sets of lights 5 times to get 5 different answers and even if you could it would take ages and be rather pointless task.

I think you just need to colour in some more bulbs on 5 of the strings and write down what the resulting fractions are, so 3 bulbs out on a string of 6 is 1/2, 2 bulbs out on a string of 3 is 2/3 etc.

Thank everyone, this is now making more sense

It's very poorly worded op so you're not being silly at all. If it helps, I have a Maths A Level and I don't get it Grin

'Change the number of broken bulbs on each set and write the new fraction' - so you just break one or two more on each string, then write what the fraction would be for each.

The 'do this 5 times' throws me. I've no idea - it's not possible. There are 6 sets overall so it can't mean make one change for each set. And some of the strings have less than 5 bulbs to start with, so you can't break up to 5 more on each set iyswim?

maybe they mean 5 times in total

Tomboyinatutu · 24/11/2015 01:12

I think it says do it five times because you can't change the one with two lightbulbs (1/2) into a different fraction

Appallingly worded question though

MaidrinRua · 25/11/2015 09:27

I'm assuming they want you to write the fraction of unbroken bulbs? No?
