I'm pretty sure that you multiply 10x by 6. Since it is length by width those are the length and the width.
Glad I could help!
Answer:
none of the answers listed are equivalent to b (22/5, 11/8, 2/5, 1/4)
Step-by-step explanation:
![\frac{1}{3b} = \frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3b%7D%20%3D%20%5Cfrac%7B4%7D%7B5%7D)
to simplify, cross multiply
(1 · 5 = 3b · 4)
(5 = 12b)
divide both sides by 12 to isolate b,
![\frac{5}{12} =\frac{12b}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B12%7D%20%3D%5Cfrac%7B12b%7D%7B12%7D)
![\frac{5}{12} = b](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B12%7D%20%3D%20b)
None of the answers listed are equivalent to 5/12

<span>In general, if you want x y ths of a number, you multiply it by xy . Let's seek the answer to your question step by step: One tenth of 400 is 110×400=40 1 10 × 400 =40 . One quarter of one tenth of 400 is 14×40 1 4 × 40 , since we found in step 1 thatone tenth of 400 is 40 , and this is equal to 10 .</span>plx mark brainlist
