Question

Since I withdrew money from my bank account, the (number, amount) of money in the account is now (fewer, less).

Short answer

The completed sentence should read: 'Since I withdrew money from my bank account, the amount of money in the account is now less.'

Step-by-step solution

Determining the Appropriate Words

First, we need to understand the difference between 'number' and 'amount'. 'Number' is used with countable nouns, whereas 'amount' is used with uncountable nouns. Money, being uncountable, will therefore be referred to as an 'amount'. The same principles apply to 'fewer' and 'less'. 'Fewer' is used with countable nouns, 'less' with uncountable nouns. Therefore, the appropriate word to use is 'less'.
