Answer:
Sophia is 17 years old. Sophia's brother is 11 years old.
Step-by-step explanation:
To reduce<span> a </span>fraction to lowest terms<span> (also called its simplest form), divide both the numerator and denominator by the GCD. For example, 2/3 is in </span>lowest<span> form, but 4/6 is not in </span>lowest<span> form (the GCD of 4 and 6 is 2) and 4/6 can be expressed as 2/3.
38/80= 19/40</span>
The teacher ordered the students in 24 ways.
We have given that the total number of students is 4.
4 students are assigned to give presentations.
We have to find the arrangement of the 4 students.
<h3>What is the arrangement?</h3>
An arrangement (or ordering) of a set of objects is called a permutation. (We can also arrange just part of the set of objects.)
In a permutation, the order that we arrange the objects n is important.
4 students can be arranged by 4! ways.

Therefore option 3 is correct.
The teacher ordered the students in 24 ways.

3x+4y=10 is in standard form. The standard form is Ax+By=C and this equation suits that form with A as 3, B as 4, and C as 10.
