James' keyboard is missing 1/7 of the consonants and two vowels. How many keys are missing in total? (Remember there are 5 vowels and 21 consonants in the alphabet.)
First find how many consonants are missing: 21 consonants * 1/7 = 
<gadget id="calculator">21*1/7</gadget>
<output>3</output>
3 consonants.
Then add the number of missing vowels to find the total number of missing keys: 3 consonants + 2 vowels = 
<gadget id="calculator">3+2</gadget>
<output>5</output>
5 keys.
