To solve the equation, we need to find a common denominator for the fractions 3/5 and 4/7. The least common multiple (LCM) of 5 and 7 is 35.
Multiplying the numerator and denominator of the first fraction by 7, we have:
3/5 * 7/7 = 21/35
Multiplying the numerator and denominator of the second fraction by 5, we have:
4/7 * 5/5 = 20/35
Now we can add the two fractions:
21/35 + 20/35 = 41/35
Therefore, 3/5 + 4/7 equals 41/35.

To solve the equation, we need to find a common denominator for the fractions 2/3 and 1/4. The least common multiple (LCM) of 3 and 4 is 12.
Multiplying the numerator and denominator of the first fraction by 4, we have:
2/3 * 4/4 = 8/12
Multiplying the numerator and denominator of the second fraction by 3, we have:
1/4 * 3/3 = 3/12
Now we can add the two fractions:
8/12 + 3/12 = 11/12
Therefore, two-thirds plus one-fourth equals 11/12.
Multiplying the numerator and denominator of the first fraction by 4, we have:
2/3 * 4/4 = 8/12
Multiplying the numerator and denominator of the second fraction by 3, we have:
1/4 * 3/3 = 3/12
Now we can add the two fractions:
8/12 + 3/12 = 11/12
Therefore, two-thirds plus one-fourth equals 11/12.

To solve the equation, we need to find a common denominator for the fractions 7/10 and 2/3. The least common multiple (LCM) of 10 and 3 is 30.
Multiplying the numerator and denominator of the first fraction by 3, we have:
7/10 * 3/3 = 21/30
Multiplying the numerator and denominator of the second fraction by 10, we have:
2/3 * 10/10 = 20/30
Now we can subtract the second fraction from the first fraction:
21/30 - 20/30 = 1/30
Therefore, (7/10) - (2/3) equals 1/30.
Multiplying the numerator and denominator of the first fraction by 3, we have:
7/10 * 3/3 = 21/30
Multiplying the numerator and denominator of the second fraction by 10, we have:
2/3 * 10/10 = 20/30
Now we can subtract the second fraction from the first fraction:
21/30 - 20/30 = 1/30
Therefore, (7/10) - (2/3) equals 1/30.

To solve the equation, we need to find a common denominator for the fractions 7/12 and 3/8. The least common multiple (LCM) of 12 and 8 is 24.
Multiplying the numerator and denominator of the first fraction by 2, we have:
7/12 * 2/2 = 14/24
Multiplying the numerator and denominator of the second fraction by 3, we have:
3/8 * 3/3 = 9/24
Now we can subtract the second fraction from the first fraction:
14/24 - 9/24 = 5/24
Therefore, (7/12) - (3/8) equals 5/24.
Multiplying the numerator and denominator of the first fraction by 2, we have:
7/12 * 2/2 = 14/24
Multiplying the numerator and denominator of the second fraction by 3, we have:
3/8 * 3/3 = 9/24
Now we can subtract the second fraction from the first fraction:
14/24 - 9/24 = 5/24
Therefore, (7/12) - (3/8) equals 5/24.
