Question

38 - (-16) , -1 7\10 - (-5) , - 5\8 - (-7\12) , 5\9 - 2 , -7*7\24 - 4 13\16

Answer 1

38 - (-16)=38+16=54,

-1 7\10 - (-5)= -1 7/10+4 10/10=3 3/10,

- 5\8 - (-7\12)=-5/8+7/12=-15/24+14/24=-1/24,

5\9 - 2=5/9-1 9/9=-1 4/9,

-7*7\24 - 4 13\16=-49/24-77/16=-98/48-231/48=-329/48=-6 41/48

Answer 2

38-(-16)=54
-1,7-(-5)=-1,7+5=5-1,7=3,3
-5/8-(-7/12)= 7/12-5/8=14/24-15/24=-1/24
5/9-2=-13/9=-1 4/9
-7*7/24-4 13/16=2 37/48

Answer 3

Let's solve each of these expressions step by step:

1. 38 - (-16) To subtract a negative number, we can change the sign and perform addition: 38 + 16 = 54

2. -1 7/10 - (-5) To subtract a negative number, we can change the sign and perform addition: -1 7/10 + 5 = -1 7/10 + 5 + 10/10 = -1 + 5 + 7/10 = 4 7/10

3. -5/8 - (-7/12) To subtract a negative number, we can change the sign and perform addition: -5/8 + 7/12 To add fractions, we need a common denominator, which is 24 in this case: (-5/8) * (3/3) = -15/24 (7/12) * (2/2) = 14/24 Now, we can add the fractions: -15/24 + 14/24 = -1/24

4. 5/9 - 2 Convert 2 to a fraction with a denominator of 9: 2 = 18/9 Now we can perform the subtraction: 5/9 - 18/9 = -13/9

5. -7 * 7/24 - 4 13/16 Convert the whole number to a fraction with a denominator of 24: 4 = 4 * 24/24 = 96/24 Now, we can perform the subtraction: -7 * 7/24 - 96/24 To subtract fractions, we need a common denominator: (-7 * 7/24) - 96/24 = -49/24 - 96/24 = -145/24

So, the final results are:

1. 38 - (-16) = 54
2. -1 7/10 - (-5) = 4 7/10
3. -5/8 - (-7/12) = -1/24
4. 5/9 - 2 = -13/9
5. -7 * 7/24 - 4 13/16 = -145/24
