What are the rules for adding and subtracting negative numbers?

1 answer:

4 0

A negative sign and a negative sign next to each other is a positive sign ex..

-14 - -3
= -14 + 3
= -11

a negative sign and a positive sign next to each other is a positive sign ex..

-14 + -3
= -14 - 3
= -17

the bigger a negative number the smaller it is
the bigger a positive number the larger it is
which supports the rule if you are subtracting the
number will become smaller and if you are adding
the number will become larger

What number is 15% of 43

Annette [7]

Step-by-step explanation:

So when a question asks what is x% of the y number. It's asking you to convert the x into decimal form by dividing by 100 and then multiply it by y. This gives you the equation: $y * \frac{x}{100}$ which gives you x% of y. so 15% of 43 is $43 * \frac{15}{100} = 6.45$ . 43% of 300 is $300 * \frac{43}{100} = 129$ .

the 12% of what number is 43 is a bit more tricky. It's asking you to instead find a number in which 12% of it is equal to 43. So instead of plugging solving for the percentage (which is already given) you solve for y. This gives you the following equation: $y * \frac{12}{100} = 43$ . Now all you do is calculate 12/100 which gives you $y * 0.12 = 43$ . now divide both sides by 0.12 to solve for y. This gives you $y = 358.\overline{33}$

43 is what percent of 106? This question is also a bit tricky, but instead of solving for y, you're solving for x. So plug in the known values, which gives you the equation: $106 * \frac{x}{100} = 43$ . Divide both sides by 106 to get $\frac{x}{100} \approx 0.406$ and now multiply both sides by 100. this gives you $x \approx 40.57$ which is the answer 40.57%

What percent of 43 is 6. This is asking the same thing just in a different way. So percentage = unknown, entire number = 43, entire number * percentage = 6. With these values we get the equation: $43 * \frac{x}{100} = 6$ . Divide both sides by 43 to get $\frac{x}{100} \approx 0.140$ now multiply by 100 to get $x \approx 13.95$ which is the answer 13.95%
