Work out 2/3 + 3/4?
Work out 5 times 3/4?
PLEASE HELP ASAP!!!

Answers

Answer 1

Answer: 2/3 + 3/4

First, we need to find a common denominator.

2*4/3*4 = 8/12

3*3/4*3 = 9/12

Now add the numerators.

9+8 = 17

17/12 = 1 5/12

Answer: 1 5/12

5 * 3/4 =

5/1 * 3/4 = 15/4

15/4 = 3 3/4

Answer: 3 3/4

Answer 2

Answer: 2/3 + 3/4
For this, you want to cross multiply
To do this, you do the first numerator (2) multiplied by the second denominator (4), and the first denominator (3) multiplied by the second numerator (3).If you draw lines between the two numbers you are multiplying, a 'cross' is made. Add these two numbers together to make the new numerator. For the denominator, multiply the bottom two numbers.
Next simplify the new fraction (Follow attached image)

5 x 3/4
This can be written as 5 x 3 / 4
5 x 3 = 15
15/4 = 3 3/4 or 3.75

What is the value of x?

x/4 = 14/16

Answers

Divide by 4. $\n (14:4)/(16:4)= (3.5)/(4) \n$ $\n \boxed{x=3.4} \n$

Divide 16/4 to get 4, then divide 14/4, to give you the answer of x=3.5.

Determine the whether the sum of 7/8 and 4/9 is closest to 0,1,2,or 3

Answers

Whenever you add fractions it means you need a common denominator. The quickest way to find this number is to multiply the two denominators together (in this case 8 and 9).
So your new fractions are 63/72 and 32/72. When you add those you get 95/72.
Next simply divide the two numbers to get a decimal, so here we get: 1.31944...
So this number is closer to 1

the pizza slice served at O'Connor's pizza place are 1/4 of a whole pizza. There are three pizzas ready to be served. 14 children come in for lunch. Is there enough pizza for every child? please explain your thinking, LOL PLZ HELP WITH MY MATH HOMWORK? THX 12 POINTS

Answers

No there will not be enough. Think about it this way. If each slice is 1/4 of the pizza, then each pizza can only feed 4 people. If you have 3 of these pizzas, then you can feed 12 people at most. Since there are 14 kids, you won't have enough.

4 pieces/1 pizza= x pieces/3 pizzascross multiplyx= 12 piecesnot enoughhope this helps

Taylor and Morgan would like to spend some time on the river while camping with their family. Taylor wants to rent a two-person kayak. There is a $5 setup fee for kayak rentals and then kayaks are rented at $8 per hour. The setup fee for canoes is $9 and they are rented at $6 per hour. Determine the number of hours it takes for canoe rentals and kayak rentals to cost the same amount.

Answers

Answer:

After 2 hrs canoe rentals and kayak rentals cost would be same.

Step-by-step explanation:

Let the number of hours be 'x'.

Given:

Set up fee for Kayak rental = $5

Hourly rate for Kayaks rental = $8

Solution:

First we will find the total cost of Kayak rentals.

total cost of Kayak rentals can be calculated by sum of Set up fee for Kayak rental and Hourly rate for Kayaks rental multiplied by number of hours.

framing in equation form we get;

total cost of Kayak rentals = $5+8x$

Now Given:

Set up fee for Canoe rental = $9

Hourly rate for Canoe rental = $6

Now we will find the total cost of Canoe rentals.

total cost of Canoe rentals can be calculated by sum of Set up fee for Canoe rental and Hourly rate for Canoe rental multiplied by number of hours.

framing in equation form we get;

total cost of Canoe rentals = $9+6x$
