10 men can complete a work in 8 days and 10 children take 16 days to complete the same workhow many days will 5 men and 10 children Wiil take to complete the work?
1 man would take 80 days to complete the work, so 1 man in 1 day would complete 1/80 of the work. 1 child would take 160 days to complete the work, so 1 child in one day would complete 1/160 of the work. In 1 day, 5 men and 10 children could do 5/80 + 10/160 = 1/16 +1/16 = 1/8 of the work. It would take them 8 days to do the job.

How do you work out inverse proportions?
Firstly you have to work out how long it would take one person to do the task. You know that 1 person would take longer to do something than say 4. So you multiply it. More people will take less time to do something. So you divide the total of 1 persons work between them. Dont worry if it turns out as a decimal. Hope I could help
How long would it take to earn 1 million pounds?
You need to be very clear to distinguish between earn and make. People is some jobs can make 1 million pounds in a year or less but that does not mean they earn it!
