To solve 4-1 1/4+1/2, we first convert the mixed number 1 1/4 to an improper fraction:
1 1/4 = (4*1 + 1)/4 = 5/4
Now we can substitute the converted fractions into the original equation:
4 - 5/4 + 1/2
Next, we need to find a common denominator for the fractions 5/4 and 1/2. The least common denominator (LCD) is 4:
4 * (4/4) - 5/4 + 2/4
Simplifying further:
16/4 - 5/4 + 2/4
Now we can combine the numerators over the common denominator:
(16 - 5 + 2)/4 = 13/4
Therefore, the answer is C) 2 1/4 (or 2 1 4).
1 1/4 = (4*1 + 1)/4 = 5/4
Now we can substitute the converted fractions into the original equation:
4 - 5/4 + 1/2
Next, we need to find a common denominator for the fractions 5/4 and 1/2. The least common denominator (LCD) is 4:
4 * (4/4) - 5/4 + 2/4
Simplifying further:
16/4 - 5/4 + 2/4
Now we can combine the numerators over the common denominator:
(16 - 5 + 2)/4 = 13/4
Therefore, the answer is C) 2 1/4 (or 2 1 4).

Find the sum..
−3/2 + 8/5
−3/2 + 8/5
To find the sum of -3/2 and 8/5, we need to find a common denominator.
The least common denominator (LCD) of 2 and 5 is 10.
Rewriting the fractions with the LCD:
-3/2 = -15/10
8/5 = 16/10
Now, we can add the fractions:
-15/10 + 16/10 = 1/10
Therefore, the sum of -3/2 and 8/5 is 1/10.
The least common denominator (LCD) of 2 and 5 is 10.

425.82 − (−120.75)
425.82 − (−120.75)
To simplify 425.82 - (-120.75), we can rewrite the expression as the sum of the two terms:
425.82 + 120.75
Adding the two numbers together:
= 546.57
Therefore, the simplified answer is 546.57.
425.82 + 120.75
Adding the two numbers together:
= 546.57
Therefore, the simplified answer is 546.57.
Evaluate this expression.
−86.4 + 16.38.
−86.4 + 16.38.
To evaluate the expression -86.4 + 16.38, we simply need to add the two numbers together:
-86.4 + 16.38 = -70.02
Therefore, the evaluated expression is -70.02.
-86.4 + 16.38 = -70.02
Therefore, the evaluated expression is -70.02.
