Sound waves with higher amplitudes sound louder than sound waves with lower amplitudes. Constructive interference will make a sound louder while destructive interference will make a sound quieter. Two waves that add together may have different frequencies.
Answer:
1 13/20
Step-by-step explanation:
You add 2 1/10 and 3 to get 5 1/10. Then you subtract, 6 3/4 minus 5 1/10. If you want to find the least common factors you get 6 15/20 and 5 2/20 to make it easier to subtract. Finally, you get 1 13/20.
I hope this helped :)
