Answer:
15:20
Step-by-step explanation:
We can simplify the ratio to 3:4
after doing that we can multiply both sides by 5 giving us
15:20 as our answer
Or you can cross multiply
9 : 12 = 15 : x
Now we have 9x = 180
divide both sides by 9 and we get
x=20
which would work giving us the ratio of 9 : 12 = 15 : 20
Answer:
10 ornaments
Step-by-step explanation:
You would have to divide 5 feet by how much it takes to make an ornament, 1/2 foot.
= ![\frac{5}{1} / \frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B1%7D%20%2F%20%5Cfrac%7B1%7D%7B2%7D)
To divide by a fractions, you will need to multiply the first number by the number you're dividing by's reciprocal:
= ![\frac{10}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B1%7D)
= ![10](https://tex.z-dn.net/?f=10)
Answer:
![x = - 16](https://tex.z-dn.net/?f=x%20%3D%20%20-%2016)
Step-by-step explanation:
Let's solve:
![\frac{3}{4} x = - 12](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B4%7D%20x%20%3D%20%20-%2012)
Step 1: Multiply both sides by 4/3.
![( \frac{4}{3} )*( \frac{3}{4} x)=( \frac{4}{3} )*(−12)](https://tex.z-dn.net/?f=%28%20%5Cfrac%7B4%7D%7B3%7D%20%29%2A%28%20%5Cfrac%7B3%7D%7B4%7D%20x%29%3D%28%20%5Cfrac%7B4%7D%7B3%7D%20%29%2A%28%E2%88%9212%29)
![x = - 16](https://tex.z-dn.net/?f=x%20%3D%20%20-%2016)
