Answer 1

Answer:

A. $1\frac{5}{21}$

Step-by-step explanation:

You have to subtract so you'll find a common denominator:

3 4/7 - 2 1/3

The common denominator in 3 and 7 is 21.

3 4/7 (you multiply 7 x 3 to get to 21 so you have to do it to the top too on the numerator you have to multiply it by 3)

3 4/7 = 3 12/21

2 1/3 (same here except you have to multiply 3 by 7x and the numerator too)

2 1/3 = 7/21

Now you can subtract:

 3 12/21

- 2 7/21 (3 - 2 = 1) (12 - 7 = 5) (Denominator always stay the same unless you can reduce).

= 1 5/21
