Which is greater 1/4 or 3/4

Answers

If we are to compare which among the given fractions is smaller, we first determine the decimal equivalent of each. If we are to solve for those, we determine that 3/4 is equal to 0.75 and 1/4 is equal to 0.25. This is done by dividing the numerator by the denominator. Comparing 0.75 and 0.25, we can conclude that 0.75 or 3/4 is greater compared to 0.25 or 1/4.

several friends each had 2/5 of a bag of peanuts left over from the baseball game.they realized that they could have bought two fewer bags between them. How many friends went to the game?

Answers

Answer:

5 friends.

Step-by-step explanation:

Let x be the number of friends,

Since, each had 2/5 of a bag of peanuts left over,

Thus, the total numbers of bag left = 2/5 of the number of friends,

$=(2)/(5)x$

According to the question,

$(2)/(5)x=2$

$\implies x = 5$

Hence, there were 5 friends.

the answer is 5.
Since each friend had 2/5 left, if you multiply that fraction by 5, you get 2.

8)If there are 4 yellow, 2 blue, 1 red, and 3 green marbles in a bag, what is theprobability you choose a blue marble at random, P(blue)?
What is the Pſyellow)?

Answers

Answer: P(blue)=1/5. P(yellow)=2/5.

Step-by-step explanation: First find the total number of marbles. 4+1+2+3=10. To find the probability of blue marbles, use this equation (number of blue marbles (2) / total number of marbles(10) ). 2/10=1/5.

To find the probability of yellow marbles do this equation (number of yellow marbles (4) / total number of marbles (10) ). 4/10=2/5.

Which of the following are solutions to the equation below? Check all that apply. 9x^2-64=0A. 8
B. -8
C. -3/8
D. 3/8
E. -8/3
F. 8/3

Answers

Answer:

E. -8/3

F. 8/3

Step-by-step explanation:

9x^2-64=0

Add 64 to each side

9x^2-64+64 = 0+64

9x^2 =64

Divide each side by 9

9x^2/9 = 64/9

x^2 = 64/9

Take the square root of each side

sqrt(x^2) = ±sqrt(64/9)

We know that sqrt(a/b) = sqrt(a)/sqrt(b)

x = ±sqrt(64)/sqrt(9)

x = ± 8/3
