I’m doing equations with rationals. The question is: David is building wooden picture frames. Each frame requires 3/4 of wood. If David started with 12 feet of wood and now only has 6 feet remaining, how many picture frames has he built.

David was able to make 8 picture frames !

Step-by-step explanation:

Here we have  , David is building wooden picture frames. Each frame requires 3/4 of wood. If David started with 12 feet of wood and now only has 6 feet remaining, We need to find  how many picture frames has he built. Let's find out:

David initially had 12 feet of wood and he's making frame which requires 3/4 of wood . Let David make x number of frames and now he's left with only 6 feet wood So , Following is the equation framed according to given scenario :

⇒

⇒

⇒

⇒

Therefore, David was able to make 8 picture frames !

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2

the answer is:

mean: 6

mad: 2.14
