You basically would use how long they are. If you had a strip of 1/2 and a strip of 3/4... with blocks they wouldn't be the same length. The 3/4 blocks would be greater.
However if you matched a 1/2 strip with a 3/6 strip, you can see that they are the same length and are equivalent.
Of course their is a way to do it mathematically but let me know if you want to see that.
Answer:
2.09<2.1
Step-by-step explanation:
2.09 < 2.1
Take one number and subtract the other.
If you get a positive, then the first number is larger. If you get a negative, then the second number is larger.
I think 2.1 is larger
2.1
-2.09
-------------
Borrow from the 1
2. 0 10
-2. 0 9
---------------
0. 0 1
Since this is positive, 2.1 is larger
This is the solutions to the question
Answer:
No solution.
Step-by-step explanation:
The equation 2x + 8 = 2(x + 5) has no solution as we see if we simplify it:
2x + 8 = 2x + 10
2x - 2x = 10 -8
0 = 2 which is absurd.
X=7. The two segments on the bottom as well as on the diagonal are the same length. This shows that the entire triangle and the inner triangle on the right are similar. So if we call the length of the bottom 2y, then 84/2y=6x/y. Solving this we get 84=12x, and so x=7
