Liam has 6 pencils. Noah has twice as many pencils as Liam. Jacob has 1/3 as many pencils as Noah. How many pencils do the boys have altogether?

22 pencils

Step-by-step explanation:

Using key words and expressions, you can find the number of pencils each boy has and then add them together to find the sum:

Liam: 6 pencils

Noah: 'twice as many' as Liam or 6 x 2 = 12 pencils

Jacob: '1/3 as many as Noah' or 12 x 1/3 = 4 pencils

6 + 12 + 4 = 22 pencils total
