Answer 36

8 - 7 1/4 can be calculated as follows:

8 - 7 1/4 = 32/4 - 29/4
= (32 - 29)/4
= 3/4

Therefore, 8 - 7 1/4 equals 3/4.

Answer 37

To subtract −4 5/11 from −2 4/11, you can follow these steps:

Step 1:
Convert both mixed numbers to improper fractions.
-4 5/11 = -49/11
-2 4/11 = -26/11

Step 2:
Now, subtract the fractions:
(-49/11) - (-26/11)
= -49/11 + 26/11
= (-49 + 26)/11
= -23/11

Therefore, -4 5/11 - 2 4/11 equals -23/11.

Answer 38

Apologies for the error. You are correct. The correct calculation is:

-4 5/11 - 2 4/11 = -49/11 - 26/11 = (-49 - 26)/11 = -75/11

Therefore, -4 5/11 - 2 4/11 equals -75/11. Thank you for catching that mistake.

Answer 39

Apologies for the confusion. Let's recalculate it correctly:

-4 5/11 - 2 4/11 can be calculated as follows:

Step 1: Convert both mixed numbers to improper fractions.
-4 5/11 = -49/11
-2 4/11 = -30/11

Step 2: Subtract the fractions:
(-49/11) - (-30/11)
= -49/11 + 30/11
= (-49 + 30)/11
= -19/11

Therefore, -4 5/11 - 2 4/11 equals -19/11.

Answer 40

Apologies for the misunderstanding. Let's recalculate with the correct expression:

To subtract 4 5/11 from 2 4/11, we can follow these steps:

Step 1: Convert both mixed numbers to improper fractions.
4 5/11 = 49/11
2 4/11 = 26/11

Step 2: Subtract the fractions:
(26/11) - (49/11)
= (26 - 49)/11
= -23/11

Therefore, 4 5/11 - 2 4/11 equals -23/11.

Answer 41

Apologies for the repeated errors. Let's recalculate the expression correctly:

To subtract 4 5/11 from 2 4/11, we can follow these steps:

Step 1: Convert both mixed numbers to improper fractions.
4 5/11 = (4 * 11 + 5)/11 = 49/11
2 4/11 = (2 * 11 + 4)/11 = 26/11

Step 2: Subtract the fractions:
(26/11) - (49/11) = (26 - 49)/11 = -23/11

Therefore, 4 5/11 - 2 4/11 equals -23/11.

Answer 42

Apologies for the repeated mistakes. You are correct, I made an error in my previous response. The correct calculation would be:

To subtract 4 5/11 from 2 4/11, we can follow these steps:

Step 1: Convert both mixed numbers to improper fractions.
4 5/11 = (4 * 11 + 5)/11 = 49/11
2 4/11 = (2 * 11 + 4)/11 = 26/11

Step 2: Subtract the fractions:
(26/11) - (49/11) = (26 - 49)/11 = -23/11

Therefore, 4 5/11 - 2 4/11 equals -23/11.

Answer 43

To subtract -4 5/11 from -2 4/11, we can follow these steps:

Step 1: Convert both mixed numbers to improper fractions.
-4 5/11 = -(4 * 11 + 5)/11 = -49/11
-2 4/11 = -(2 * 11 + 4)/11 = -26/11

Step 2: Subtract the fractions:
(-26/11) - (-49/11) = (-26 + 49)/11 = 23/11

Therefore, -4 5/11 - (-2 4/11) equals 23/11.

Answer 44

To find the difference between 907.907 and 709.709, we can subtract them:

907.907 - 709.709 = 198.198

Therefore, the answer is 198.198.

Answer 45

To find the difference between 90.897 and 81.725, we can subtract them:

90.897 - 81.725 = 9.172

Therefore, the answer is 9.172.

Answer 46

To simplify the expression 12 8/15 − 7 + 7/15 + 15, we can follow these steps:

Step 1: Convert the mixed number 12 8/15 to an improper fraction:
12 8/15 = (12 * 15 + 8)/15 = 188/15

Step 2: Rewrite the expression with the new fraction:
188/15 - 7 + 7/15 + 15

Step 3: Combine like terms:
(188/15 + 7/15) + 15 = 195/15 + 15

Step 4: Simplify the fraction by finding a common denominator:
(195 + 225)/15 = 420/15

Step 5: Simplify the fraction further by dividing both the numerator and denominator by their greatest common divisor (in this case, 15):
420/15 = (28 * 15)/(1 * 15) = 28/1

Therefore, 12 8/15 − 7 + 7/15 + 15 simplifies to 28/1 or simply 28.

Answer 47

To simplify the expression 12 8/15 - 7 + 7/15 + 15, we can follow these steps:

Step 1: Convert the mixed number 12 8/15 to an improper fraction:
12 8/15 = (12 * 15 + 8)/15 = 188/15

Step 2: Add the fractions and whole numbers separately:
188/15 - 7 + 7/15 + 15

Step 3: Combine the fractions:
(188/15 + 7/15) = 195/15

Step 4: Simplify the fraction:
195/15 = 13

Step 5: Add the final whole number:
13 + 15 = 28

Therefore, the simplified answer to 12 8/15 - 7 + 7/15 + 15 is 28.

Answer 48

Answer 52

To subtract 30.87 from 189.987, we can follow these steps:

189.987 - 30.87 = 159.117

Therefore, 189.987 - 30.87 equals 159.117.

Answer 53

To find the balance in Mark's account after the bank charged a $25 fee, we can subtract the fee from the initial balance:

Balance after fee = Initial balance - Fee
Balance after fee = -$11 - $25
Balance after fee = -$36

Therefore, the balance in Mark's account after the fee is -$36.

Answer 54

To determine the water level at the end of summer, we need to subtract the additional drop of 2 1/3 meters from the initial level of 1 1/2 meters below sea level.

Step 1: Convert the mixed numbers to improper fractions:
1 1/2 = (1 * 2 + 1)/2 = 3/2
2 1/3 = (2 * 3 + 1)/3 = 7/3

Step 2: Subtract 7/3 from 3/2:
3/2 - 7/3 = (9/6) - (14/6) = -5/6

Therefore, at the end of summer, the water level is 5/6 meters below sea level.
