The result is TR (20).
To determine the result of TR (915) - TR (895), the following logical-mathematical reasoning must be made:
We find a constant that is repeated in both values, which is TR.
In turn, both values have a different quantity, which multiplies that constant.
Therefore, you must perform this multiplication and then subtract the results, to obtain the final result.
- TR (915) - TR (895) = X
- 915TR - 895TR = X
- 20TR = X
Therefore, the result is TR (20).

This is a simple proportion problem. On the left side of the colon : there's a 1 and xy. On the right it's yz and a 2. This means for every one xy there will be two yz. So, if there are 2 xy there are 4 yz
Answer:
the number of black tokens in the bag is 2
Step-by-step explanation:
The computation of the number of black tokens in the bag is as followS
Given that
There is 8 green tokens
and, the ratio of green tokens to black tokens is 4:1
So let us assume the black tokens be x
So,

Now do the cross multiplication
x = 2 tokens
Hence, the number of black tokens in the bag is 2

First subtract 11

Then divide by negative four
Then you'll get x= 2
So the answer is 2
