Answer:
80
Step-by-step explanation:
If we consider 10s as a block, we would be asking how many blocks (of 10) does 800 have?
We can figure it out by dividing 800 by 10. That is the NUMBER OF TENS 800 will have. So,
800/10=80
Hence, there are 80 tens in 800.

x ----> the original price of a video game
we know that
1) The price of a video game increases by 20%

The final price is equal to the original price multiplied by 1.20
so
2) The price of a video game decreases by 10%
so
The final price is equal to the price at this moment multiplied by 0.90
so

In order to make a fraction as large as possible, you want the numerator to be large, and the denominator to be small.
Using the counting numbers, the smallest denominator (x - y) you can make is ' 1 '.
Now you just have to make the numerator large. You do that simply by using the largest two numbers you have available . . . 49 and 50 .
Now the fraction is (49 + 50) / 1 = 99 .
