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

what i would say the best answer is a. 40.5

ratio is 2 : 9

the answer is three

13.5 : 3
