Answer:
372
Step-by-step explanation:
We know that a ratio of 3 : 2 has 5 people, so figuring out how many times that ratio goes into our total number helps us find the value of the total number of adults.
930 / 5 = 186
This means that there are 186 groups of 3 children to 2 adults
So, in each of the 186 groups, there are 2 adults.
Therefore, we can multiply (186)(2)
to find the total number of adults: 372
The number of the children and adult will be 558 and 372.
What are ratio and proportion?
A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
At a swimming pool, the ratio of children to adults was 3 : 2.
C / A = 3 / 2
Then solve the equation for C, then the equation will be
C = (3/2)A
The total number of the people is 930. Then the equation will be
C + A = 930
Substitute the value of C in the above equation. Then the equation will be
(3/2)A + A = 930
(5/2)A = 930
A = 930 x (2/5)
A = 372
The number of the adult will be 372.
Then the number of the children will be
C + 372 = 930
C = 930 – 372
C = 558
The number of the children will be 558.
Thus, the number of the children and adult will be 558 and 372.
