Well, if you mean: 42 divided by 2 divided by 1, then here is the answer.
Just take it step by step:
42 divided by 2 = 21
21 divided by 1 = 21
Pretty simple.
1 over 2 divided by 1 over 4 is 2.
Finding the answer to 3 divided by 4 - 1 divided by 4 is the same as finding the answer to 3/4 (three quarters) - 1/4 (one quarter). In this instance, 3/4 - 1/4 = 2/4, which can be simplified to 1/2, or one half.

Not necessarily. 1 1/2 divided by 2 = 3/4. 4 1/2 divided by 2 = 2 1/4.
4
2 and 1/4 divided by 3/4 = 3

4 divided by 2 is 2 - 1 is 1 x 3 is 3 plus 4 is 7

1/2
Division comes before addition, so 2 divided by 3 is 2/3, and 4 divided by 6 is 2/3, and 2/3 + 2/3 =4/3, which is 1 and 1/3.
0.5 = 1/2 and 0.25 = 1/4 1/2 divided by 1/4 is changed to 1/2 multiplied 4/1 which is 2 This rule applies when dividing a fraction by a fraction.
If your question is what is:(2/5) + (3/4) - (1/2) = ?then your answer would be (.4) + (.75) - (.5) = .65However, if your question is what is:2/5+3/4-1/2=?then your answer would be 2/5=.4+3=3.4/4=.85-1=-.15/2=-.075
1x2/4 = 2
