The ratio between the ages of Ola, Asmaa, and Heba is . If the difference between the ages of Ola and Asmaa is 10 years, determine the Heba's age.
We can use the concept of "the difference of parts" to solve this problem.
The ratio of Ola's age to Asmaa's age to Heba's age is . So, Ola's age parts, Asmaa's age parts, and Heba's age parts.
The difference between Ola's age and Asmaa's age parts 6 parts parts.
Since 2 parts years, then one part years years.
To find Heba's age, multiply the number of parts by the value of one part: years years. So, Heba is 35 years old.
