This question already has an answer here:

I am stuck in choosing the correct verb (is or are) for the following sentence, since generation is uncountable (singular agreement) and it is preceded by multiple percentages (plural agreement).

Which one should I use?

70, 40, 10, 60, and 10% of the old generation is/are selected randomly for the crossover, mutation, swap, reversion, and insertion operators, respectively.

  • @Davo mine is a bit more specific in terms of its different percentages. – Sajjad SAberi Sep 11 '17 at 11:09
  • No, as stated your question is a duplicate. However, if you are asking whether multiple percentages require a different verb, then you should make that clear in the question. It would also help to reference the other (nominated) question and say exactly why it doesn't help. – Andrew Leach Sep 11 '17 at 11:25
  • Would you say 'Half of the men is bachelors'? – Edwin Ashworth Sep 11 '17 at 11:33
  • @AndrewLeach as can be implied, i insist on the particularity of my question, exactly because there are, as you kindly said, multiple percentages concerning an uncountable noun right after that. – Sajjad SAberi Sep 11 '17 at 11:33
