B:11/20>5/9
C:11/20=5/9

Answers

Answer 1

Answer:

Answer:

$(11)/(20)<(5)/(9)$

A is correct.

Step-by-step explanation:

Given: $(11)/(20)\text{ and }(5)/(9)$

We need to compare the two fraction.

We can compare either greater , less or equal.

If we compare two fraction. First we make their denominator same.

Denominators are 20 and 9

We will find the LCD of 20 and 9

20 = 2 x 2 x 5

9 = 3 x 3

LCD = 2 x 2 x 3 x 3 x 5 = 180

$\text{First Fraction}\rightarrow (11* 9)/(20* 9)\Rightarrow (99)/(180)$

$\text{Second Fraction}\rightarrow (5* 20)/(9* 20)\Rightarrow (100)/(180)$

Now, we can see their denominator are same.

We will compare the numerator.

99<100

Thus,

$(99)/(180)<(100)/(180)$

$(11)/(20)<(5)/(9)$

Hence, $(11)/(20)<(5)/(9)$ correct.

Answer 2

Answer: $(11)/(20) =(11 * 9)/(20 * 9)=(99)/(180) \n \n(5)/(9)=(5 * 20)/(9 * 20)=(100)/(180) \n \n 99<100 \Rightarrow (99)/(180)<(100)/(180) \Rightarrow \boxed{(11)/(20) < (5)/(9)} \Leftarrow \hbox{answer A}$

I desperately need help with this question????? I got 2 different answers and don't know which one is right. So please help me here is the question Students from three classes at Hudson valley elementary school are planning a boat trip. On the trip there will be 20 students in each class along with 11 total teachers and 13 total parents. Each boat seats 10 people. How many boats will they need to rent? Explain how you solved the problem

Answers

each class has 20 students

3 classes // 20 x3= 60

60 students + 11 teachers+13 parents = 84 people total

as you cant put half people in boats you round up to 90

meaning you would need 9 boats to have enough space for all of them xx

hope this helped x

They will need to rent 5 boats. 20+11+13=44 and each boat seats 10 people so 44÷10= 4 remainder:4 and you cant keave 4 people out they need another boat.
