1÷ $\frac{1}{9}$

Convert 1 to a fraction

$\frac{1}{1}$ ÷ $\frac{1}{9}$

Using the KFC rule (or some equivalent)

KEEP the first fraction

FLIP the sign

CHANGE the second fraction

$\frac{1}{1}$ × $\frac{9}{1}$ = $\frac{9}{1}$ = 9

Answer:

Step-by-step explanation:

To divide a fraction, you turn it into a multiplication problem by reciprocating the fraction.

Reciprocating means making the numerator the denominator and the denominator, the numerator. For instance, 2÷3/4 becomes 2×4/3

1÷1/9=1/1 × 9/1=9

The farmer needs to buy fertilizer to spread on his garden. The garden is a 20 x 15 rectangle. A bag of fertilizer covers 30 ft.

Ainat [17]

Answer:

$10$

Step-by-step explanation:

The area of a rectangle is given by $A=lw$ , where $l$ is the length of the rectangle and $w$ is the width of the rectangle. Therefore, the area of a 20 x 15 rectangle is equal to $20\cdot 15=300\:\mathrm{ft^2}$ .

Since one bag of fertilizer covers 30 square feet, the farmer needs $\left \lceil \frac{300}{30}\right \rceil=\boxed{10}$ bags of fertilizer.

Solving Systems of Linear Equations by graphing. 3y+4x=3 and x+3y=-6. Can someone help me with where the lines intersect and sho

Greeley [361]

The best way to do this question is to use elimination. Elimination is a way to find out the POINT OF INTERSECTION between two lines. Let me show you how.

3y+4x=3
x+3y=-6

Elimination is a way to remove any same variable with the same coefficient. In this case, there is 3y in both equations. In this case, we subtract to eliminate.

3y-3y+4x-x=3+6 It's plus 6 because two negatives become positive.
3x=9 Divide both sides by 3
x=3

Now you can find y.

x+3y=-6
3+3y=-6
3y=-9
y=-3

Therefore, the POI is (3,-3). I hope you understand this. Make sure to mark as brainliest.

Answer: 10.

Step-by-step explanation:

DIVISION. 120/12.

That is hard! Here's a trick.

12x9= 99=9=108. Or 12x6=66+6=72.

We will stick with 12x9, that equals 108.

We should add another 12 until we get to 120.

108+12=120. That is 10 times. The trick was...

dividing by 12 is hard, so lets say 12x4. I can put 4 and 4 together.

44 then and another 4. That is 48. So 12x4=48.
