How do you subtract mixed numbers with like denominators?
You can either subtract the whole number portions, then subtract the numerators, or you can convert the mixed numbers to improper fractions, subtract the numerators, and simplify. For example, 3 5/7 - 2 1/7 can be handled as 3 - 2 and 5/7 - 1/7, or as 26/7 - 15/7; either way, it's 1 4/7.
Is subtract to take numbers apart?
Subtract is to take away a certain portion of a number. For example, if you subtract 5 from 7 (7-5), you take off 5 parts of 7, and get 2 as your answer.
7 plus 8x-5 equals 8x plus 7-5x?
7+8x-5 = 8x+7-5x Subtract 7 from both sides: 8x-5 = 8x-5x Subtract 8x from both sides: -5 = -5x Divide both sides by -5: x = 1 So the equation implies x = 1
What is the range of 6 8 5 7 3 1?
7 You take the lowest number and subtract it from the highest. 8-1=7
What is 2 and 1 8th subtract 1 and 7 8th?
It is: 2 and 1/8 subtract 1 and 7/8 = 1/4

1. Subtract 25 2. Then subtract 6 3. Then subtract 12 4. Then subtract 2 5. Then subtract 10 6. Then subtract 15 7. Then subtract 7 8. Then add 3 X 1/2 9. Then add 8
How do you subtract five sevenths from 1?
You turn the 1 into an improper fraction (7/7) that is equal to 1. 7/7 - 5/7 = 2/7
What is seven and one fourth minus five and one eighth?
7 1/4 - 5 1/8 Change to common denominator 7 2/8 - 5 1/8 Subtract the whole numbers, then subtract the numerators of the fractions, don't subtract the denominators, just leave them as they are, and combine the results. 7-5 = 2 2-1 = 1 Answer: 2 1/8
What is 7 over 8 subtract 5 over 8 equal?
7/8-5/8= 1/4
What is 8 and 1 over 6 minus 2 and 5 over 6?
8 1/6 - 2 5/6 = 5 1/3. Here's how I did it. Borrow a 1 from the 8 and change it to 6/6 & add to 1/6, so you have 7 and 7/6. Subtract 5/6 from 7/6 = 2/6, which equals 1/3. Subtract 2 from 7 = 5.

7 plus 8x-5 equals 8x plus 7-5x?
7+8x-5 = 8x+7-5x Subtract 7 from both sides: 8x-5 = 8x-5x Subtract 8x from both sides: -5 = -5x Divide both sides by -5: x = 1 So the equation implies x = 1
What is the range of 6 8 5 7 3 1?
7 You take the lowest number and subtract it from the highest. 8-1=7
Why do you need a common denominator to add and subtract fractions?
To get the correct answer. If you were adding 1/5 and 1/7, you might not know that the answer is 12/35 unless you knew that 1/5 = 7/35 and 1/7 = 5/35
How many numbers are between 773 and 1000?
Let's start with an easier problem. If you want to know how many numbers are between 1 and 7, then you have 2 & 3 & 4 & 5 & 6 which is 5 numbers. If you subtract 1 from 7, then you have 6 numbers. So, to get the final answer you subtract the two original numbers and then subtract one more. In our example, 7 - 1 = 6 and 6 - 1 = 5, so the answer is 5 numbers between 1 and 7. For the given example, take 1000 - 773 to get 227, then subtract one more. So, there are 226 numbers between 773 and 1000.
7 over 8 subtract 5 over 8?
(7/8)-(5/8) =2/8 =1/4 or .25
