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

<em>9. </em>

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

<em>10.</em>

Explanation: Same process as question 9.

Answer: -4/1/12

<em>11. </em>

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

<em>12. </em>

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

Answer: 3/107/200

<em>13. </em>

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.

<em>14. </em>

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

Answer:

-2/-3

Step-by-step explanation:

(75, 60) (45, 40)

75       60               since 75 is larger than 45, we subtract = -30

45       40               since 60 is larger than 40, we subtract = -20

= -20/-30

reduce

= -2/-3

s344n2d4d5 [400]

Nikita's distance from her for the second part of the race was 1.5 kilometers.

Since Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour) without training beforehand, and in the first part of the race, her average speed was 8.75 kilometers per hour, while for the second part of the race, she started to get tired, so her average speed dropped to 6 kilometers per hour, to determine which expression represents Nikita's distance for the second part of the race the following calculation must be performed:

  • 8.75 x 0.65 + 6 x 0 = 5.68
  • 8.75 x 0.50 + 6 x 0.15 = 5.275
  • 8.75 x 0.40 + 6 x 0.25 = 5
  • 100 = 60
  • 40 = X
  • 40 x 60/100 = X
  • 24 = X
  • 39 - 24 = 15
  • 15 = 1/4 hour
  • 6/4 = 1.5

Therefore, Nikita's distance from her for the second part of the race was 1.5 kilometers.
