Answer:
A is proportional
B and C are <u>NOT</u> proportional
Step-by-step explanation:
First, simplify 588 and 60:
<u>588 divided by 6</u>
60 divided by 6
= <u>98</u>
10
Simplify them again by dividing them both by 2
= <u>49</u>
5
Let's look at A:
441 and 45
Simplify by dividing by 9
= <u>49</u>
5
It's pretty obvious that A is <u>proportional</u> because the simplified values are exactly the same.
Next, let's check B:
215 and 25
Simplify by dividing by 5
= <u>43</u>
5
Now that its simplified you can compare
<u>43</u> is smaller than <u>49</u>
5 5
B is <u>not proportional</u>
<u />
Finally, let's check C:
649 and 110
Simplify by dividing by 11
= <u>51</u>
10
Make <u>51</u> and <u>49</u> have the same denominator so we can compare them
10 5
<u>51</u> can stay the same because 5 times 2 equals 10
10
<u>49 times 2</u>
5 times 2
= <u>98</u>
10
Now that the denominators are the same we can compare
<u>51</u> is much smaller than <u>98</u>
10 10
Therefore, C is also <u>not proportional.</u>
