We want to add the following 2 fractions:
Denominator 1 ≠ Denominator 2.We need matching denominators
Multiply fraction 1 numerator * fraction 2 denominator.
Multiply fraction 2 numerator by the fraction 1 denominator
We add those 2 results, and get our numerator.
Our denominator is the product of the denominators of both fractions.
| Fraction 1 + Fraction 2 = | Numerator 1 x Denominator 2 + Numerator 2 x Denominator 1 |
| Denominator 1 x Denominator 2 |
| Fraction 1 + Fraction 2 = | 1 x 7 + 1 x 3 |
| 3 x 7 |
| Fraction 1 + Fraction 2 = | 7 + 3 |
| 21 |
| Fraction 1 + Fraction 2 = | 10 |
| 21 |
| Answer = | 10 |
