Find two consecutive odd integers whose sum is 111.

all work shown, !

Two consecutive odd integers are indefinite

Step-by-step explanation:

Theory :

If two numbers are added or subtract then, the nature of result is given by

ODD+EVEN=ODD

ODD+ODD=EVEN

EVEN+EVEN=EVEN

Given that sum of two consecutive odd integers is 111.

Here, Result is 111 and it is odd number.

Therefore, By adding two consecutive odd integers and getting result as 111 which is odd number is impossible.

Thus, Two consecutive odd integers are indefinite

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
