Mr. wong spent 2/3 of his workday selling products and the rest of his workday making phone calls. what fraction of his workday did he spend making phone calls

1/3

Step-by-step explanation:

if he has spent 2/3 of his workday selling products that is almost his whole day.  He has 1/3 of his workday left so he dedicated it to making calls for his company.  

So you work if you subtract 2/3 from a whole that leaves you with 1/3 of your day left

What information do I already have?

Mr. Wong's total workday is 3/3 because 3/3 = 1.

We already know Mr. Wong spent 2/3 of his workday selling products.

Now, the word problem tells us that he spent the rest of his day making phone calls. "The rest of his day" is a key sentence/phrase!

What does "...spent the rest of his day..." mean anyways?

It means that you should subtract!

Therefore:

3/3 - 2/3 = 1/3

There's your answer!

what is the original number? you forgot to add it.
