A 1/5
B 8/10
C 42/5
D 1/10
Please help.

5 dozen - 3 dozen = 2 dozen

5 books - 3 books = 2 books
so,
5/10 - 3/10 = 2/10
now, which answer is equal to 2/10 ?

As for the other answers, I guess I'd have to see the other questions, yeah?

1/10?

2. 1/2 + 3/4

A 2/3
B 4/6
C 1 2/4
D 13/24

3. 1/6 + 3/8

A 4/6
B 4/8
C 4/14
D 13/24

4.

A 11/24
B 2/24
C 2/8
D 2/12

I forgot the question for 4 is 7/8 - 5/12

5. The sum of two numbers is 7/8. One addend is 3/4. What is the other?

A 4/4
B 1/8
C 1/4
D 2/8

A 1/5

A is correct for the first one.

What do you get for the others?
To add fractions, you always need to use a common denominator.

To find the difference between fractions, you need to have a common denominator. The common denominator is the least common multiple (LCM) of the denominators. In this case, the denominators are 10 and 10, so the LCM is 10.

Once you have a common denominator, you can subtract the numerators and keep the common denominator. So, let's subtract the numerators:

5/10 - 3/10 = (5 - 3)/10 = 2/10

Simplifying the fraction, we can divide both the numerator and the denominator by their greatest common divisor (in this case, it's 2):

2/10 รท 2/2 = 1/5

Therefore, the answer is A) 1/5.
