Yes, you can but you need to "rename" the whole part of the first mixed number.

How do you determine a difference when subtracting two integers that have the same signs?
(-10) - (-5) = (-5) when subtracting a negative number from another negative number if the first number is larger that the second number then you just subtract the to numbers. don't worry about the signs just subtract the numbers when your done put the sign of the first number on again.
.7 recurring as a fraction?
Call your number "x", and calculate 10 times that number.10x = 7.777...x = 0.777...Subtract the second equation from the first, and you get:9x = 7If you solve this for "x", you get the number as a fraction. In this case, it is 7/9.
What are two mathods of comparing numbers?
One option for comparing two numbers is to subtract the first number from the second number. If the result is less than zero, the first number is larger. If the result is greater than zero, the second number is larger. If the result is zero, the numbers are equal. Another option (for positive numbers) would be to divide the first number by the second number. If the result is greater than one, the first number is larger. If the result is less than one, the second number is larger. If the result is one, the numbers are equal. This rule flips if you are comparing negative numbers.
How can you compare rational numbers?
Subtract one from the other.If the answer is positive then the first is larger,if the answer is negative, then the second is larger.Rational numbers are numbers that can be expressed as fractions whereas irrational numbers can't be expressed as fractions.
How do you do subtract mixed number?
To subtract mixed numbers, convert the fractions into ones with a common denominator, make the first fraction larger than the second, subtract, then reduce the result if necessaryExample : 6 1/8 - 2 3/4Find the common denominator -- here it is 81/8 = 1/8 and 3/4 = 6/8 (you cannot subtract the fractions because the second is larger)So borrow from the whole number by making 6 1/8 into 5 9/8 (1= 8/8)Now 5 9/8 - 2 6/8 can be subtracted to yield 3 3/8---* More on "borrowing" to make the fraction larger : what you are doing is turning one of the whole numbers into an equal fraction and adding it to the fraction. Here we took 1 from the 6 making it 5, and added that 8/8 to the 1/8 to make the improper fraction 9/8. So the terms 6 1/8 and 5 9/8 have the same value.
What numbers add up to 10?
Choose any number for the first number. Subtract 10 minus the number you chose to get the second number.
How do you do mixed number division?
You invert the second fraction then divide the whole numbers and there is your answer
How will you subtract whole numbers when the digits on the second numbers is longer than the first number?
Answer: you will just have a minus number Answer: You subtract the other way, and then put a minus sign in front. Example: 7 - 15 = - (15 - 7) = -8.
Which pair of numbers has a sum of 100?
There are infinitely many solutions for that. Choose ANY number as the first number. The subtract 100 minus this number, to get the second number.

What to numbers tha can be added to make 43?
This, of course, has infinitely many solutions. Choose ANY number for the first number. Then, subtract 43 minus your first number, to get the second number.
What numbers add up to be negative 11?
Choose ANY number as the first number. Subtract -11 minus your number to get the second number.

Is the sum of any three consecutive counting numbers always divisible by 3?
Yes. Choose any three consecutive counting numbers. The first number is the second number subtract 1 The third number is the second number add 1 Adding the three numbers together is the same as adding: (the second number subtract one) plus the second number plus (the second number add one). The "subtract one" and "add one" cancel each other out to leave the sum as: the second number plus the second number plus the second number Which is the same as 3 times the second number, ie the sum is a multiple of 3 and so is divisible by 3. For example: 10 + 11 + 12 = (11 - 1) + 11 + (11 + 1) = 11 - 1 + 11 + 11 + 1 = 11 + 11 + 11 + (1 - 1) = 11 + 11 + 11 + 0 = 11 + 11 + 11 = 3 x 11
How can you determine if a number is rational?
If the number can be expressed as a ratio of two integer (the second not zero) then the number is rational. However, it is not always a simple matter to prove that if you cannot find such a representation, then the number is not rational: it is possible that you have not looked hard enough!
