Question

Liwen and Celina shared some plants in a ratio of 5:6. Celina decided to give Liwen 2/3 of her plants, which left her with 21 fewer plants than Liwen. How many plants do they have altogether?

Answer 1

Answer: 231

Explanation:

Liwen    Celina

   5x          6x

5x - 21 = $(\frac{2}{3})$6x

5x - 21 = 4x

-4x +21   -4x +21

  x        =        21

Liwen: 5x   = 5(21)   = 105

Celina: 6x   = 6(21)   = 126

                       Total:   231
