Answer:
The age of brothers are 4 years and 2 years respectively.
Step-by-step explanation:
We are given that the ages of two brothers have a ratio of 2 to 1. When 4 years have passed, the ratio of their ages will be 8 to 6.
Let the age of the first brother be 'x years' and the age of the second brother be 'y years'.
So, according to the question;
- The first condition states that the ages of two brothers have a ratio of 2 to 1, that means;
-------------- [equation 1]
- The second condition states that when 4 years have passed, the ratio of their ages will be 8 to 6, that means;





= 2 years
Putting the value of y in equation 1 we get;
x = 2y
x =
= 4 years
Hence, the age of brothers are 4 years and 2 years respectively.

Answer:
It equals a negative number because there's a negative and a positive which will result in a negative answer
Step-by-step explanation:
if there's a negative and a positive the result will be negative
if it's two negative result would be positive :
-1 × -1 = +1
-1 × +1 = -1
+1 × +1 = +1
-1 × -1 × -1 = -1
-1 × -1 × +1 = +1
They are both SI units of measurements
