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.
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
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 number best completes the sequence 7 1 5 - 3 7?
The sequence appears to be alternating between addition and subtraction operations. Starting with 7, we subtract 6 to get 1, then add 4 to get 5, subtract 8 to get -3, and then add 10 to get 7. Following this pattern, the next operation would be subtraction, so we subtract 12 from 7 to get -5. Therefore, the number that best completes the sequence is -5.
