I’m not sure what steps i’m doing wrong but i got -1/2

1/2

Step-by-step explanation:3=6/2

6/2-5/2=1/2

Idk maybe you’re writing 3 as 4/2 or you’re changing 1/2 to -1/2

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

the answer is:

mean: 6

mad: 2.14
