<span>Add all whole numbers together 6 + 4 + 9 = 19 </span> <span>Then all fractions together 1/2 + 2/3 + 1/4 = find least common denominator 12 so you get: 6/12 +8/12+3/12 = 17/12 </span> <span>If the fraction has access like 17/12 convert to fraction so working back words you definitely know 12 will be on bottom so 5 has to be numerator and you left with 1 as a whole number so you get 14/12 >>>1 and 5/12 </span> <span>Next you add 19 plus 1 5/12 = 20 5/12
So the answer is the last option 20 5/12 yards.</span>
PH can be calculated using the following equation pH = -log [H₃O⁺] for apple juice the hydronium /hydrogen ion concentration is 0.0003 pH = -log (0.0003) pH = 3.5 correct answer is C
For ammonia pH = -log (3.1 x 10⁻⁹) pH = 8.5 answer should be 8.5
