The reciprocal of a number is simply 1 divided by that number. In this case, the reciprocal of 2 and 3 over 7 would be 1 divided by 2 and 3 over 7. To find the reciprocal, you would flip the fraction, making it 7 over 2 and then take the reciprocal, which is 1 over 7/2 or 1 divided by 7/2. To divide by a fraction, you multiply by its reciprocal, so 1 divided by 7/2 is the same as 1 times 2/7, which simplifies to 2/7.
1/2 + 1/3 * 1/7 = 1/2 + 1/21 = 21/42 + 2/42 = 23/42
