For the following problems, fill in the blanks with rational numbers. show work proving that your numbers create true statements. (do not use -1 and 1)

a. 6, - 9

b. 100, - 7

c. 0.25, - 5

Step-by-step explanation:

Here in these problems we have to fill up the blanks with rational numbers other than -1 and 1.

a. Let us assume that x and y are the numbers respectively in the blacks to be filled.

So, xy = (- 18) × 3 = - 54.

Therefore, x maybe 6 and y maybe - 9 and they will give the  product as - 54 (Answer)

b.  Let us assume that x and y are the numbers respectively in the blacks to be filled.

So, .

Therefore, x maybe 100 and y maybe - 7 (Answer)

c.  Let us assume that x and y are the numbers respectively in the blacks to be filled.

So, xy = - 1.25

Therefore, x maybe 0.25 and y maybe - 5. (Answer)

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
