7/15 / (3/5)
Flip the 2nd fraction and multiply:
7/15 * 5/3
Multiply the numerators and denominators together:
35/45
Divide 5 to the numerator and denominator:
35 / 5 = 7
45 / 5 = 9
7/9
2 slices are left left because if you change the 8 to a fraction it will turn to this 8/8 and you need to change 3/4 to have the same denominator as the 8/8 so 3/4 will turn to 6/8 and then you subtract 8/8 by 6/8 and itll be 2/8 left so the answwer is 2 slices left
That is the pH scale
pH = - log of the concentration of hydrogen ions in a solution.
