Answer:
56 : 28 as 122 : 61
Step-by-step explanation:
Proportion says that two ratios or fractions are equal.
As per the statement:
56 : 28 :: 122 : ?
Let x be the fourth proportion.
then;
56 : 28 :: 122 : x
by definition of proportion:
![\frac{56}{28}=\frac{122}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B56%7D%7B28%7D%3D%5Cfrac%7B122%7D%7Bx%7D)
by cross multiply we have;
![56x = 3,416](https://tex.z-dn.net/?f=56x%20%3D%203%2C416)
Divide both sides by 56 we have;
x = 61
Therefore, 56 : 28 as 122 : 61
If it has the negative so the answer will be negative but if it doesn't have the negative so the answer is positive because if you want to find the m you should divide the both sides of the equation by the factor of m:
-4m = 1.75 ⇒ -4m/-4 = 1.75/-4 ⇒ m = 1.75/-4 ⇒ m = -0.4375
4m = 1.75 ⇒ 4m/4 = 1.75/4 ⇒ m = 1.75/4 ⇒ m = 0.4375 :)))
i hope this is helpful
have a nice day
Simple because 1/3 = two of 1/6.
So if you make 5 copies of 1/3 then you should make 10 copies of 1/6.
I'm guessing the length is 4, the width is 6 and the height is 2.8,
67.2 is the answer and the units are m^3
