To find equivalent ratios just factor the same number to both numerator and denominator. I will make the ratios simple by multiplying 2/2 and 3/3 to the originals. To check, set as fraction and cross multiply and you should have the same number. I will show you how to check by doing it to the first ratio.
8:5 16:10 24:15
Check:
8/5 = 16/10
(8)(10)=(5)(16)
80=80
8/5=24/15
(8)(15)=(5)(24)
120=120
4:19 8:38 12:57
6:23 12:46 18:69
The product of denominators can always serve as the common denominator. The appropriate choice is ...
... z times u . . . . . . . the first choice
Answer: Georgia used 10 dollies and she has left 4 dollies .
Step-by-step explanation:
Given: Georgia bought a package of of 14 dollies to use in her valentines.
Therefore, the number of dollies in a package = 14
If she used
of the package to make her in valentines.
The number of dollies she used = ![\frac{5}{7}\times14=5\times2=10](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B7%7D%5Ctimes14%3D5%5Ctimes2%3D10)
The number of dollies left = ![14-10=4](https://tex.z-dn.net/?f=14-10%3D4)
Hence, Georgia used 10 dollies and she has left 4 dollies .
U would factor by grouping and get x^2(x-2) + 3(x-2) and then get (x^2 +3) (x-2)
Gcf is the greatest common factor. THe gcf of 98 and 42 is 14
