Question

Pls help, i wasn't paying much attention in class and this seems pretty hard for me :(

Answer 1

Answer: 9= -1.5 or -3/2

               10= -11/6 or 1.8333

                11= -10.9

                 12= 3.535

                   13= Town A is -3.33 Town B is -3 2/5, 2/5= .44, so town B is colder, as it is -3.44

                     14= I'm not sure about number 14, sorry about that

Answer 2

9.

Explanation: So for question 9, you need to find the LCD (Least common denominator) so you list out the multiples of 8 and 4, when doing so, you find out that 8 is the LCD of both, since 8 is both a multiple of itself and of 4.

So, to get the answer, you do 4 * 2 and anything you do to the denominator (bottom number), you do to the nominator (top number).

So now you have -8/3/8 +6/2/8 then you just add the nominators and whole numbers like normal. You get, -2/1/8 (Remember you are adding a positive number to a negative number.)

Answer: -2/1/8

10.

Explanation: Same process as question 9.

Answer: -4/1/12

11.

Explanation: Read -7.3 out loud, it would be negative seven and 3 tenths, that makes it easy to convert as a fraction. It would be -7/3/10. Do the same for the other number, and you have -3/6/10, then you just add. You get -10/9/10.

Answer: -10/9/10

12.

Explanation: Same process as question 11. (You're in the thousandths now.) You get 3/535/1000. Reduce.

Answer: 3/107/200

13.

Explanation: You have 2 options here, to convert the decimal into a fraction, or to convert the fraction into a decimal, I'll be changing the fraction into a decimal, you wanna write it as a 10 as a denominator, so to get to 10 you multiply the denominator by 2, and anything you do to the denominator, you do to the nominator. So, -3/2/5 as a decimal is: -3.4, then you go ahead and compare them and you can see that the temperature in town A is colder.

Answer: The temperature in town A is colder.

14.

Explanation: For this one, you just subtract or add the amount to 7number. The dates don't matter, just telling you to do it in that order.

60.68 + 75.50 = 136.18

136.18 - 25.16 = 111.02

111.02 - 82.05 = 28.97

28.97 + 59.95 = 88.92

Answer: $88.92
