How is the process used to divide fractions similar to the process used to multiply fractions?

Answers

Answer 1

Answer:

Answer:

When we are multiplying any two fractions, we do the following:

$(a)/(b) *(c)/(d)$

And when we are dividing two fractions, we do the following:

$( (a)/(b) )/( (c)/(d) )$

We solve such problems by multiplying but we take the reciprocal of denominator.

It will look like $(a)/(b) *(d)/(c)$

So, basically we are multiplying in both conditions. This is why these are similar.

Answer 2

Answer: Well when you divide fractions you are actually using multiplication. Dividing is the same as multilying by the reciprocal

Toni can carry up to 18 lb in her backpack. Her lunch weighs 1 lb, her gym clothes weigh 2 lb, and her books (b) weigh 3 lb each. How many books can she carry in her backpack?

Answers

Toni can carry five books in her backpack. You must start by subtracting the weight of the other required items. Toni's lunch which is one pound and gym clothes which are two pounds. This can be calculated by 18-1-2=15. Toni has 15 pounds left to carry books. She should divide this by the weight of each book, which is three pounds. 15/3=5. Therefore, Toni can carry five books.

Answer:

600,000 km²

Step-by-step explanation:

Using the exponential regression calculator : the regression fit obtained for the data is :

36510 * (1.08^x)

After 40 years ;

x = 40

Hence,

y = 36510 * 1.08^40

y = 36510 * 21.72452

y = 793,162.27 km

Hence, y is closest to 800,000 km

X^{2} -25=0 Please help meeee

Answers

Answer:

$x=5,x=-5$

Step-by-step explanation:

$x^2-25=0$

Add 25 to both sides:

$x^2-25+25=0+25$

$x^2=25$

Square root both sides:

$x=√(25),\:x=-√(25)$ (Since a negative number multiplied by itself gives positive, there are two answers.)

$x=5,x=-5$

Hey there!

ANSWER: $x=5\nx=25$

EXPLANATION:

$x^2-25=0$

The first step we have to do is to add 25 to both sides of the equation.

$x^2-25+25=0+25\n\text {equals }x^2=25$

In our last and final step, we will have to take the square root.

$x=$ ± $√(25)$

We have two answers.

$x=5(ANSWER)\nx=-5(ANSWER)$

Hope this helps!
