A teacher is teaching her class sign language. She wants to teach a total of 35 signs. She taught one-fifth of the signs one week. She taught two-sevenths of the signs the next week. What percentage of the total signs did she teach in these two weeks? Round your answer to the nearest tenth of a percent.

(1/5 + 2/7) x 100% = 48.6 %
