3 3/4 * 1/4

First I would turn 3 3/4 into an improper fraction

15/4 * 1/4

Now multiply

15/8

And now you can make a mixed number again

1 7/8

And there's your answer :P

Anon is correct! :) You can also just think about it as 7 x 5 and then add the two 0s, that you "took off"

At least that's how I usually figure it out :P

First you need to add up all the prices

3.65 + 4.25 + 3(.99) + 6.75

Simplify

3.65 + 4.25 + 2.97 + 6.75

Add

17.62

Now multiply that by 5.5 to find out what the tax added is

96.91

Move the decimal over to the left twice

.96 cents

Now add that to 17.62

18.58

And there's your answer! :)

NOTE: There is a very likely chance that this is wrong because now I realize I'm not really sure why I multiplied and moved the decimal over. Just a warning :) It may just be right though! But maybe wait until someone else answers :P

Haha it really does take a bit of time, but it's fun to help out. Thank you CPhill!! :)

I remember making a little thing about this about a year ago but I probably wouldn't be able to find it so I'll just recreate it again! (With examples)

Positive and Positive

I'm just assuming you already know how positives work :)

Adding:

1 + 2 = 3

Subtracting:

1 - 2 = -1

Multiplying:

1 x 2 = 2

Dividing:

1 ÷ 2 = 0.5

Postive and Negative (and vice versa)

Adding:

Whenever there is a negative during adding, if it is before the addition sign and there is a positive number after, just think of it as you have negative, but since you're adding a positive, it's taking away a negative. If there is a negative after the addition sign, the negative cancels out the positive and it turns into for example, 1 - 2 instead of 1 + (-2)

-2 + 1 = -1 or 1 + (-2) = -1

Subtracing:

Whenever there is a negative during subtracting, if it is before the subtraction sign and there is a positive number after, you simply subtract, so the negative number becomes bigger (technically smaller, but hopefully you get my drift). If there is a negative after the subtraction sign, the two negatives cancel out and turn into addition. (ex: 1 - (-2) = 1 + 2)

-2 - 1 = -3 or 1 - (-2) = 3

Multiplying:

Whenever there is a negative and a positive during multiplication, the negative always wins. The answer is always negative no matter whether the negative number is before or after the multiplication symbol.

-2 x 1 = -2 or 1 x -2 = -2

Dividing:

Whenever there is a negative and a posititive during division, it works the same as multiplication. The negative always wins.

-2 ÷ 1 = -2 or 1 ÷ -2 = -0.5

Negative and Negative

Adding:

Whenever there are two negatives during adding, the negative cancels out the addition sign and turns it into a subtraction sign

-1 + (-2) = -3 or -2 + (-1) = -3

Subtracting:

Whenever there are two negatives during subtracting, the negative and the subtraction sign cancel out and turn into addition.

-1 - (-2) = 1 or -2 - (-1) = -1

Multiplying:

Whenever there are two negatives during multiplication, the two negatives cancel out and the answer is always positive

-1 x -2 = 2 or -2 x -1 = 2

Division:

Whenever there are two negatives during division, they act the same as multiplication. The two negatives cancel out and the answer is always positive

-1 ÷ -2 = 0.5 or -2 ÷ -1 = 2

Hopefully this helps! :) Let me or anyone else know if you need more help or still don't understand

10.34/18.80 = x/100

Cross multiply

18.80x = 1034

Divide by 18.80 on both sides

x = 55

Now, subtract 55 from 100 since you're trying to find the amount discounted

100 - 55

Simplify

45%

And that's your answer :)

Thanks CPhill! :) It's good to see you by the way

2x - 6y = 12

Insert 0 for y

2x - 6(0) = 12

Simplify

2x = 12

Divide by 2 on both sides

x = 6

x - int = 6

Use original equation and insert 0 for x this time

2(0) - 6y = 12

Simplify

- 6y = 12

Divide by -6 on both sides

y = -2

y - int = -2

I wasn't sure if you were trying to find the x and y intercepts, but that's the only thing I could think of with that equation!

Sorry if that wasn't what you were trying to find

Next time just use the calculator, but :

21 + 8 = 29

1,000,000 ÷ 10 = 100,000

Note: Whenever you divide a number by 10, the decimal point (1,000,000.) goes to the left once (1,000,00.0 = 100,000)
