Answer:

(i) Associative property of addition.

(ii) Commutative property of addition.

(iii) Inverse property of addition.

(iv) Identity property of addition.

Step-by-step explanation:

Associative property of addition: If a, b and c are three number, then

$a+(b+c)=(a+b)+c$

Commutative property of addition: If a and b are two number, then

$a+b=b+a$

Inverse property of addition: The sum of a number and its additive inverse (-a) is 0.

$a+(-a)=0$

Identity property of addition: The sum of a number and identity element 0 is the same number.

$a+0=a$

By using the above definitions we can say that

(i) A + (B + C) = (A + B) + C is Associative property of addition.

(ii) A + B = B + A is Commutative property of addition.

(iii) A + (−A) = 0 is Inverse property of addition.

(iv) A + 0 = A is Identity property of addition.

Solutions

We know that a spinner was divided into many different color sectors. Some sectors are larger than others. The spinner was spun 300 times. The results were tallied up and were written in a table.

Red:93

Blue:59

Green:105

Yellow:43

The spinner landed the highest on green. To find the probability that the next spin will land on green we have add all the numbers and simplify them.

93 + 59 + 105 + 43 = 300

Out of 300 the spinner landed to green 105 times. We have the fraction 105/300.

105/300 can be reduced. To reduce the fraction we need to the GCF of 105 and 300. The GCF is 15.

We can reduce the fraction by dividing the numerator and denominator by the GCF = 15.

105 ÷ 15 = 7

300 ÷ 15 = 20

Our new fraction is 7/20

The probability that the next spin will land on green is 7/20.

To get the answer to part (B) we have to add the results of red and green then simplify.

93 + 105 = 198

The fraction is 198/300. 198/300 can be reduced. To reduce the fraction we need to the GCF of 105 and 300. The GCF is 6.

We can reduce the fraction by dividing the numerator and denominator by the GCF = 6.

198 ÷ 6 = 33

300 ÷ 6 = 50

The new fraction is 33/50

The probability that the next spin will land on either green or red is 33/50.

Answer:

each ouce is worth 25 cents

solution

in order to solve this you need to create proportions so

10 ounces

per $2.50

well you want this to be a unit rate so you would have

10 ounces = 1 ounce
