Hi guys, I'm desperate for help! "Over the following 5 years, the number of male members, at nearly 3800, was twice as much as that of female ones." In this sentence, is it true to use "twice as much as"? I think it's wrong because there is no uncountable noun here. But this sentence is from a sample essay, and it's supposed to be true. I don't know, please help me. Thanks a lot.
