Help umm how do i do this im dumb idk how to do it :(

WITH DECIMAL: the bigger the demominateor (the bottom number) is, the smaller the value of the number. for ex. 1/4 is smaller then 1/2, 1/8 is bigger then 1/16, etc.

1/4 would go in between 0 and -1 because 1/4 isn't a whole number

-3 1/4 would go in between -3 and -4 becauce 3 AND 1/2 is more then just a 3

-2 3/4 would go in between -2 and -3 becasue 2 + other 3/4 is going to be bigger than 2 but smaller than a 3

9/4 is a tricky one casue 9 is bigger then 4. so you need to see how many times 4 goes into 9 (2 times = 4 +4 = 8) so the simplfied version would be 2 1/4 casue 9 - 8 = 1. so the 9/4 would go in between 2 and 3

lastly, the 3/4 would go in between 0 and 1 becasue 3/4 is deffinately smaller than 1 and definatly bigger than 0

( are greatly appershated, commnet for help!)

529 and 531

step-by-step explanation:

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.
