2 3/5 -1 1 1/4=
A. 1 7/20
B. 1 2/9
C. 1 5/20
D. 1 1/10
To solve this equation, we need to convert all the mixed numbers to improper fractions.
2 3/5 = (2 * 5 + 3)/5 = 13/5
1 1/4 = (1 * 4 + 1)/4 = 5/4
Now we can subtract the fractions:
13/5 - 1 - 5/4
To combine the fractions on the right side, we need to find a common denominator. The common denominator of 5 and 4 is 20.
Multiplying the numerator and the denominator of 13/5 by 4 gives us 52/20.
Multiplying the numerator and the denominator of 5/4 by 5 gives us 25/20.
Therefore, 13/5 - 1 - 5/4 = 52/20 - 20/20 - 25/20
Combining the fractions gives us:
(52 - 20 - 25) / 20 = 7/20
Since 7/20 is a proper fraction, let's convert it back to a mixed number:
7/20 = 0 7/20 = 0 + 7/20 = 7/20
Therefore, 2 3/5 - 1 1/4 = 1 7/20.
The correct answer is A. 1 7/20.
2 1/2+3 3/5=
A. 6 3/10
B. 5 4/7
C. 5 1/10
D. 6 1/10
To solve this problem, we need to add the mixed numbers by converting them to improper fractions.
2 1/2 = (2 * 2 + 1)/2 = 5/2
3 3/5 = (3 * 5 + 3)/5 = 18/5
Now we can add the fractions:
5/2 + 18/5
To combine the fractions, we need to find a common denominator. The common denominator of 2 and 5 is 10.
Multiplying the numerator and the denominator of 5/2 by 5 gives us 25/10.
Multiplying the numerator and the denominator of 18/5 by 2 gives us 36/10.
Therefore, 5/2 + 18/5 = 25/10 + 36/10.
Combining the fractions gives us:
(25 + 36) / 10 = 61/10
Since 61/10 is a proper fraction, we can convert it to a mixed number:
61/10 = 6 1/10
Therefore, 2 1/2 + 3 3/5 = 6 1/10.
The correct answer is D. 6 1/10.
5-3 1/3=
2
2 2/6
1 2/3
2 2/3
To solve this equation, we need to convert the mixed number to an improper fraction.
3 1/3 = (3 * 3 + 1)/3 = 10/3
Now we can subtract the fractions:
5 - 10/3
To combine the fractions, we need to find a common denominator. The common denominator of 1 and 3 is 3.
Multiplying the numerator and the denominator of 5 by 3 gives us 15/3.
Therefore, 5 - 10/3 = 15/3 - 10/3.
Combining the fractions gives us:
(15 - 10) / 3 = 5/3
Since 5/3 is a proper fraction, let's convert it back to a mixed number:
5/3 = 1 2/3
Therefore, 5 - 3 1/3 = 1 2/3.
The correct answer is C. 1 2/3.
8 1/3-6 3/4=
2 7/12
1 7/12
1 1/7
2 2/7
To solve this equation, we need to convert the mixed numbers to improper fractions.
8 1/3 = (8 * 3 + 1)/3 = 25/3
6 3/4 = (6 * 4 + 3)/4 = 27/4
Now we can subtract the fractions:
25/3 - 27/4
To combine the fractions, we need to find a common denominator. The common denominator of 3 and 4 is 12.
Multiplying the numerator and the denominator of 25/3 by 4 gives us 100/12.
Multiplying the numerator and the denominator of 27/4 by 3 gives us 81/12.
Therefore, 25/3 - 27/4 = 100/12 - 81/12.
Combining the fractions gives us:
(100 - 81) / 12 = 19/12
Since 19/12 is a proper fraction, we can convert it to a mixed number:
19/12 = 1 7/12
Therefore, 8 1/3 - 6 3/4 = 1 7/12.
The correct answer is A. 1 7/12.
3 2/5+7 6/7=
11 9/35
10 9/35
10 2/3
10 8/35
To solve this equation, we need to convert the mixed numbers to improper fractions.
3 2/5 = (3 * 5 + 2)/5 = 17/5
7 6/7 = (7 * 7 + 6)/7 = 55/7
Now we can add the fractions:
17/5 + 55/7
To combine the fractions, we need to find a common denominator. The common denominator of 5 and 7 is 35.
Multiplying the numerator and the denominator of 17/5 by 7 gives us 119/35.
Multiplying the numerator and the denominator of 55/7 by 5 gives us 275/35.
Therefore, 17/5 + 55/7 = 119/35 + 275/35.
Combining the fractions gives us:
(119 + 275) / 35 = 394/35
Since 394/35 is a proper fraction, we can convert it to a mixed number:
394/35 = 11 9/35
Therefore, 3 2/5 + 7 6/7 = 11 9/35.
The correct answer is A. 11 9/35.
