-12 would fall into integers and real numbers.

-12 is not a natural number because it is negative.

-12 is not irrational because it can be transferred into a fraction, $- \frac{12}{1}$ .

Joanne signed up for 24 dancing lessons she took 3/4 of the by April and 1/5 of them by May .What part of dancing lesson did she

gavmur [86]

Answer:

$Part = \frac{19}{20}$

$Lessons = 23$

Step-by-step explanation:

Given:

$Dancing\ Lessons = 24$

$April = \frac{3}{4}$

$May = \frac{1}{5}$

Required:

Determine the part she took

To solve this, we simply add up the part she took in April and May.

$Part = \frac{3}{4} + \frac{1}{5}$

Take LCM

$Part = \frac{15 + 4}{20}$

$Part = \frac{19}{20}$

Hence, she took $\frac{19}{20}$ of the dancing lesson.

However, to calculate the number of lesson.

We have to multiply $\frac{19}{20}$ by the total dancing lessons.

$Lessons = \frac{19}{20} * 24$

$Lessons = \frac{19* 24}{20}$

$Lessons = \frac{456}{20}$

$Lessons = 22.8$

$Lessons = 23$ ---- Approximated

I WILL MARK AS BRANLIEST!

Answer:

0.5 pounds is one game

2 pounds is one textbook

Step-by-step explanation:

g = games

t = textbooks

Let's start with how much a game weighs. We know that when Chad added two more games the weight of the box increased by one pound (it was previously 21 pounds and then went to 22 when the two games were added). This means one game equals half of a pound (or 0.5 lbs.)...

$2g = 1$

$\frac{2g}{2} = \frac{1}{2}$ -> if you divide one side by two, you must do the same to the other.

$g = \frac{1}{2} = 0.5$

Now that we know the weight of the games, we can figure out the weight of the textbooks.

$6g + 9t = 21$ -> 6 games and 9 textbooks weigh 21 pounds.

Plugging in that each game is 0.5 pounds...

$6(0.5) + 9t = 21$

$3 + 9t = 21$

$3 - 3 + 9t = 21 - 3$

$9t = 18$

$\frac{9t}{9} = \frac{18}{9}$

$t = 2$

That means that each textbook equals 2 pounds.

I hope this helps!
