Answer:

4/13 hours

Step-by-step explanation:

Total pounds of lasagna = 4 1/3 pounds

Total time taken to cook = 1 1/3 hours

How many hours per pound did it take to cook the lasagna?

Hours per pound of lasagna = Total time taken to cook / Total pounds of lasagna

= 1 1/3 hours ÷ 4 1/3 pounds

= 4/3 ÷ 13/3

= 4/3 × 3/13

= 4/13 hours

It will take 4/13 hours to cook each pound of the lasagna

The entire family (5 people) save 120 gallons per day.

Subtraction:

Subtraction means we have to find the difference of the numbers.

Given,

A family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon per minute showerheads.

Each member of the family averages 8 minutes in the shower per day.

Here we need to find the entire family savings per day.

According to the question,

The total bath time for the whole family is,

=> 8 x 5 = 40

So for one day,

If the showerheads cost 5 gallon per minute, then the cost for the family is,

=> 40 x 5 = 200

If the showerheads cost 2 gallon per minute, then the cost for the family is,

=> 40 x 2 = 80

So, the savings is,

=> 200 - 80

=> 120

So, they save 120 gallons per day.

Can anyone help me to understand how u add,subtract,multiply and divide fractions like explain how u do it using an example:) Pl

kotykmax [81]

Adding fractions:
Lets say you have two fractions like 1/2 and 1/3. To add them, you have to make the denominator the same. So we find the least common multiple of 2 and 3, which is 6, so we multiple 1/2 by 3/3 so we have 3/6 without changing the value, and we multiple 1/3 by 2/2 to have 2/6. Then we add the numerators and have 5/6.

Subtraction fractions:
Same thing as adding, just subtracting instead.
Both need to make sure you have the same denominator.

Multiplying fractions:
This is the most simple. All you do is multiply the numerators and the denominators. So if you have 5/6 and 3/4, you multiply the numerators to have 15, the denominators to have 24, and so you have 15/24, simplified to 5/8.

Dividing fractions:
If you have 5/6 divided by 3/4, you flip the 3/4 to 4/3, and you multiply that with 5/6.

Answer:

If we were interested in how the gas prices had changed between 2002 and 2009, we could compute that the cost per gallon had increased from $1.47 to $2.14, an increase of $0.67. While this is interesting, it might be more useful to look at how much the price changed per year. You are probably noticing that the price didn’t change the same amount each year, so we would be finding the average rate of change over a specified amount of time.

The gas price increased by $0.67 from 2002 to 2009, over 7 years, for an average of

$0.677yearsapprox0.096

dollars per year. On average, the price of gas increased by about 9.6 cents each year.

hope it helps

Answer:

slope of a line is given by -A/B

Here A=5 and B= -3

so , when we plug in the values: -(5/-3) = 5/3
