More comparing decimals

Answers

When comparing, think of the signs as a crocodile. A crocodile will want to eat greater (bigger) numbers than smaller numbers. So, you can think of it as that way.

2. 0.5 < 0.8 ... 0.8 is greater than 0.5

5. 0.7 = 0.70 ... This is same. 0.70 just has an extra 0 which you don't need.

8. 2.9 > 2.8 ... 2.9 is greater since 9 is bigger than 8.

11. 0.65 > 0.36 ... 65 is greater than 36. Therefore, 0.65 is greater.

14. 4.50 > 4.05 ... 4.50 has a five in the tenth place. 4.05 has five in the hundredth place.

17. 6.01 < 6.1 ... 6.1 has a one in the tenth place. 6.01 has a one in the hundredth place.

Describe how to find the least common multiple of three number .

Answers

Take the three numbers, and list all of their prime factors. I'll use 3, 9, and 21 for an example to help.
3: 3
9: 3 x 3
21: 7 x 3
You take the times that a number occurs the most in any of the three numbers and multiply them together. 3 occurs the most in a single number twice, and 7 occurs the most in a number once.
So you'd multiply 3 x 3 x 7 to get 63.

How do you add fractions wiyh improper fractions

Answers

You add them the same way you do with proper fractions. Make sure they have common denominators and add the numerators.

Example:

$(3)/(2) + (4)/(3)$

$(3*3)/(2*3) + (4*2)/(3*2)$

$(9)/(6) + (8)/(6)$

$(9+8)/(6)$

$(17)/(6)$

The same way you do with proper ones . . . put them over a common denominator, and then add the new numerators.

I need to solve this algebra expression5-7+2x10
The answer is 18 but I don't understand why it's 18 & not 22 .
Can you explain why they subtracted instead of adding ?
Thank you

Answers

$5-7+2*10$
$5-7+20$
$-2+20=18$
The answer is :18

Ok so they subtract instead of add because if you said I could have $5 to spend at the mall for an example and I took 7 I would have to pay you back. But what happens if you take 5 away from seven is you would get -2 so you would subtract that 2x10. You subtract it because it's a negative number. Does that make sense?
