Answer:
Don't lisen to that the anwer is 0.3125
Step-by-step explanation:
To answer this youd have to set up a proportion. 5/2 is the ratio of weight on earth and mars respectively. The other side has to have the same ratio where 125lbs is the weight on earth and x is the weight on mars. The equation would look like 5/2=125/x. Youd have to cross multiply, and would get (125)(2)=5x. Solve for x to find the weight on mars
-3x=2x+19
-19 -19
-3x-19=2x
+3x +3x
-19=5x
/5 /5
x=19/5
Answer:
The answer is A
Step-by-step explanation:
10 divided by 5
To answer this question, we just need to subtract the saved cloth from the requested cloth:
![\frac{5}{6} - \frac{5}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D%20-%20%5Cfrac%7B5%7D%7B12%7D%20)
Since the fractions don't have the same denominator, we have to find the least common denominator. Luckily, since 6 goes into 12 twice, we can convert
![\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D%20)
into
![\frac{10}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B12%7D%20)
:
![\frac{5}{6}( \frac{2}{2}) - \frac{5}{12} = \frac{10}{12} - \frac{5}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D%28%20%5Cfrac%7B2%7D%7B2%7D%29%20-%20%5Cfrac%7B5%7D%7B12%7D%20%3D%20%5Cfrac%7B10%7D%7B12%7D%20-%20%5Cfrac%7B5%7D%7B12%7D)
Now that the fractions have a common denominator, we can subtract them:
![\frac{10}{12} - \frac{5}{12} = \frac{5}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B12%7D%20-%20%5Cfrac%7B5%7D%7B12%7D%20%3D%20%5Cfrac%7B5%7D%7B12%7D%20)
The difference between the requested cloth and the saved cloth is 5/12 of a foot, or 0.4166'.
