  1. The ratio of May's age to Lilian's age is 3 : 2.
  2. The ratio of Lilian's age to the total age is 2 : 5.
  3. Lilian's age is 10 and May's age is 15.
  1. The ratio of the mass of potatoes and the mass of both ingredients is 5 : 7.
  2. The fraction of  potatoes to the total mass of both ingredients is 5/7.
  3. The total mass of both ingredients is 21 kilograms.

What are the ages of Lilian and May?

Let May's age be represented with m

Lilian's age 2/3m

Ratio of May's age to Lilian's age = m : 2/3m

Multiply both sides by 3 : 3  : 2

Ratio of Lilian's age their total age: 2 : 5

Lilian's age = 2/5 x 25 = 10 years

May's age = 3/5 x 25 = 15 years

What is the total mass of both ingredients?

Let the mass of carrots be represented with c

The mass potatoes would be represented with 5/2c

Ratio of carrots to potatoes : 2 : 5

Ratio of the mass of potatoes to the total mass : 5 : 7 = 5/7

Mass of carrots = 5/2c - c = 9

3/2c = 9

3c = 18

c = 6

Mass of potatoes = 5/2 x 6 = 15

Total mass = 15 + 6 = 21 kilograms
