1 over 4 − (−5 over 8)
To subtract fractions, we need to find a common denominator.
The common denominator of 4 and 8 is 8.
So, 1 over 4 is equivalent to 2 over 8 (multiplying the numerator and denominator by 2).
Now, we can subtract fractions:
2 over 8 minus (-5 over 8) is equal to (2 + 5) over 8.
2 + 5 = 7
Therefore, the answer is 7 over 8.
260 − (−45) − 45
To solve this expression, we first simplify the subtraction of negative numbers.
260 minus (-45) is the same as 260 plus 45.
260 + 45 = 305
Now, we subtract 305 minus 45.
305 - 45 = 260
Therefore, the final result is 260.
186 − (−72)
To solve this expression, we simplify the subtraction of negative numbers.
186 minus (-72) is the same as 186 plus 72.
186 + 72 = 258
Therefore, the final result is 258.
