Is 9/10 greater than 5/6

Answers

(9)/(10) =(54)/(60)
(5)/(6) =(50)/(60)

(54)/(60) \ \textgreater \ (50)/(60)
(9)/(10) \ \textgreater \ (5)/(6)

Hi there!


To see which fraction is greater, I like to divide the numerator by the denominator of each of the fractions, and then see which decimal is larger. I'll show you what I mean. :)


9 ÷ 10 = 0.9, right? Set this answer aside.

5 ÷ 6 = 0.83


Now, we compare the two fractions. If you are having trouble setting them aside from one-another, multiply the decimals by 100 to see what your percent will be.


0.9 × 100 = 90

0.83 × 100 = 83


So, we now see that 9/10 was greater than 5/6. You were right!


Hope this helps! :D

If x is the midpoint of -21 and 18, find the value of x.
midpoint =

Answers

The distance from -21 to 18 would be 39 units ( -21 to 0 is 21 and from 0 to 18 is 18 , 21 +18 = 39)

To find the midpoint distance, divide the total distance by 2:

x = 39/2

x = 19.5

Now to find the midpoint, either add 19.5 to -21 or subtract 19.5 from 18.

Midpoint  = -1.5

Answer:

−1½ = x

Step-by-step explanation:

First, find the range in between 18 and −21, which is 39:

18 - x =  -21 \n  \n 39 = x

Take half of that range, then add that to −21:

19(1)/(2) = (39)/(2) \n  \n -21 + 19 (1)/(2) = -1(1)/(2)

In one grade of 150 students, the ratio of boys to girls is 2:3. How many boys are in that grade?

Answers

Answer:

The numbers of boys in one grade are 60 .

Step-by-step explanation:

As given

In one grade of 150 students .

The ratio of boys to girls is 2:3.

Let us assume that the scalar multiple of boys and girls be x.

Thus number of boys = 2x

Number of girls = 3x

Than the equations becomes

2x + 3x = 150

5x = 150

x = (150)/(5)

x = 30

Thus number of boys = 2 × 30

                                    = 60

Therefore the numbers of boys in one grade are 60 .


2+3 = 5

150/5 = 30

30*2 = 60

There are 60 boys in that grade.

Question 3, I give thanks and 5 stars :DJoshua has made 90% of the lay-up baskets he has attempted at basketball practice.

A. What is the probability that he will make the next three lay-up baskets he attempts? Express your answer as a decimal.


B. Write the equation you used to find this answer.

C. What does each piece of your equation represent?

Answers

A. So you know that he has a 0.9 chance of getting the basket each individual time. So just do 0.9^3 (0.9x0.9x0.9) which comes out as 0.729.

B. Oops. 0.9^3

C. The 0.9 represents the chance of getting it in the basketball net. The "cubed" represents that he attempts the shot three times.
