Sharee and her two sisters ate 3 /5 of a pizza. How much of the pizza did each girl have? A) 1 /3 B) 1/ 5 C) 2 /15 D) 3 /10

Answer:

B) 1/ 5

Step-by-step explanation:

Number of persons = Sharee and her two sisters = 3 persons

Quantity of pizza eaten = 3/5

Each person ate:

3 persons = 3/5 pizza

1 person = x pizza

Cross Multiply

3 × x = 3/5 × 1

x = 3/5 × 1/3

x = 3/5 ÷ 3

x = 3/5 × 1/3

x = 1/5

Hence, each person ate 1/5 pizza.

Step-by-step explanation:

do opposites to both sides. what is the opposite of -5? it would be plus 5.

add 5 to both sides

Lisa and bart spin the spinner 60 times
ladessa [460]
The question is not complete. It should read;
<span>Lisa and Bart spin this spinner 60 times the result are below/ black=17 blue=15 orange=21 purple=7 a. What is the experimental probability of a spin of orange? B which color had an experimental probability that matched its theoretical probability

<u>Answers</u>
a) 0.35
b)Blue

<u>Explanation</u>
The probability of an event is its chance to occur. 
Probability is found by the formula,

Probability = (Number of favourable outcome)/(Number of total outcome)
       
Part a
</span>The orange are 21 and the total spins are 60. 
Probability (orange) = 21/60
                                = 0.35

Part 2
The theoretical probability of blue is normally 25%.
By calculating the experimental probability of blue we get,
P(blue) = 15/60
            = 1/4
In percentage
1/4×100 = 25%

So, the <span>color that had an experimental probability that matched its theoretical probability is blue.</span>
