Question

Which interger is between -36/15 and -69/20?
a.3 b.2 c.-3 d.-2

Answer 1

Take a guess

Answer 2

The answer must be negative, so (a) and (b) are out right away.

You could punch the numbers into a calculator:
-36/15 = -2.4
-69/20 = -3.45
The integer must be between -3.45 and -2.4, and the only one that satisfies this requirement is (c) -3.

------------
Another way is to find the lowest common denominator (LCD) and compare the numerators. In this case, LCD = 60:
-36/15 = -36/15 * (4/4) = -144/60
-69/20 = -69/20 * (3/3) = -207/60
The integer must be between -207/60 and -144/60. Compare -2 and -3:

-2 = -2/1 = -2/1 * (60/60) = -120/60
This is NOT between -207/60 and -144/60.

-3 = -3/1 = -3/1 * (60/60) = -180/60
This IS between -207/60 and -144/60.

So the answer is (c) -3.

Answer 3

if you do the calculation you'll find that -36/15 = -35 divded by 15 = -2.4
and -69/20 = -69 divided by 20 = -3.45

The only integer between these two values is -3. So C.

Answer 4

C. -3
-36/15 = -2.4
-69/20 = -3 9/20

Answer 5

-36 /15 = -2.4

-69 /20 = -3.45

so, you read like this -5, -4, -3.45, -3, -2.5, -2.4, -2, -1, 0 1, 2, 3 ...

So the answer is -3 which is c from your list

Answer 6

c now do your home work yourself,,,,


you arent going to learn this way,,,

- 36/15= -2 6/15 which equals - 2 2/5

-69/20 = -3 9/ 20

thus -3 falls inbetween,,,

Answer 7

if u go by approximations....
1. choices (A) and (B) get eliminated coz dey r positve
2. -36/15 = a lil less than -2
3.-69/20 = a lil less dan -3

so d ans shud b -3

Answer 8

ur question is simple u hav asked that what is b/w -2.4 and -3.5
so its simple the answer is
c.-3
HAVE A NICE DAY

Answer 9

its definatly not a positive number. I would say C. -3!
