Get the two numbers into the same denominator to compare them.
The LCD of 10 and 12 is 60, but you could use 120 or 240 or whatever else.
9/10 would scale up to 54/60 (10 times 6 = 60, 9 times 6 = 54)
3/12 would scale up to 15/60 (12 times 5 = 60, 3 times 5 = 15)
Comparing 15/60 to 54/60, you could cut 3 pieces and would have 9/60 of an inch (3/20) remaining.
Answer: 6.25
Step-by-step explanation: 11.5 minus the amount you're left with.
11.5 - 5.25 = 6.25
To fact check.
6.25 - 11.5 = 5.25

Answer:
20x = 55
Step-by-step explanation:
First you have to add 3x to both sides of 11-3x=x

Now that you have 11 = 4x you divide 4 on both sides 
11/4 = x
But you can't divide 11 by 4 unless you are looking for the decimal form of 11/4 which is 2.75
so now we take 11/4 or 2.75 depending on if you need your answer in fraction or as a decimal and replace that with x however both will equal the number 55
82 degrees and 98 degrees
First, find the original equation
180 = (x) + (x + 16)
Simplify: 180 = 2x + 16
Next, use the subtraction property of equality to subtract 16 from both sides
180 - 16 = 2x + 16 - 16
Simplify: 164 = 2x
Then, you can use the division property of equality to find the value of x
164/2 = 2x/2
Simplify: 82 = x
Now, we know that the first angle equals 82 degrees and that the second angle equals 98 degrees
