Step by step explanation: To solve this you have to find a common denominator. To do this you have to multiply 1/3 (numerator and denominator) by 4 so it becomes 4/12. Then you have to multiply the numerator and denominator of 1/4 by 3 so the denominator of both fractions is 12. Now you will get. 4/12 + 3/12. To add this add the numerator and keep the denominator. Therefore it is 3+4/12=7/12
Step-by-step explanation: To add these two fractions together, we start by finding their common denominator.
The common denominator for 3 and 4 will be the least common multiple of 3 and 4 which is 12. So we multiply the top and bottom of our first fraction by 4 and the top and bottom of our second fraction by 3. That gives us 4/12 + 3/12 which simplifies to 7/12.
Therefore, 1/3 + 1/4 = 7/12 which is in lowest terms.
