Question

One third of a certain quantity exceeds one seventh of that quantity by 16. Find the quantity.​

Answer 1

Answer:

84

Step-by-step explanation:

$quantity \: = x \\ \frac{1}{3} x = \frac{1}{7} x + 16 \\ \frac{1}{3} x - \frac{1}{7} x = 16 \\ \frac{7x - 3x}{21} = 16 \\ 4x = 336 \\ x = 84$
