It will be cost $ 42.39 for 27 slices of pizza
<h3>
Further Explanation</h3>
A slice of pizza = $1.57
27 slices of pizza = the number of pizza x price/slice
= 27 x 1.57
We are going to use standard algorithm to solve this multiplication
1.57 ⇒ 2 decimal places
<u> 27</u> x ⇒ 0 decimal place
1099
<u> 314 </u>+
42.39 ⇒ 2 decimal places
In decimal number multiplication, the process is the same with the whole number multiplication. Only always remember when to put the decimal point in the answer.

Answer:
1. mean=1.5, median=1.7, mode is 1.8
2. mean=102,median=134, mode=no mode
3. mean=1885,median=2300, mode=2300
Step-by-step explanation:
3/5 = 60%
20 ÷ 5 = 4
3 x 4 = 12
Answer is A) 12/20
Based on the number of people who chose the other fruits, the percentage of people who chose pears was <u>25%. </u>
<h3>Number of people who chose pears </h3>
= Number of participants - Number who chose apples - Number who chose oranges
= 60 - 28 - 17
= 15 people
<h3>Percentage who chose pears </h3>
= Number of people who chose pears / Total number of people x 100%
= 15 / 60 x 100%
= 25%
In conclusion, 25% chose pears.
