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.
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+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
7 You take the lowest number and subtract it from the highest. 8-1=7
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
You turn the 1 into an improper fraction (7/7) that is equal to 1. 7/7 - 5/7 = 2/7
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
7/8-5/8= 1/4
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.
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+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
7 You take the lowest number and subtract it from the highest. 8-1=7
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
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.
(7/8)-(5/8) =2/8 =1/4 or .25
