Work out a) 5 3/4 - 2 1/4 b) 7 2/3 + 2 1/5

Please answer will giv brainliest

A= 3 2/4 or 3 1/2 simplified

B= 9 13/15

Step-by-step explanation:

I don't know how to do an explanation of this, its kinda complicated.

5 3/4 - 2 1/4 should be easy to subtract because it has the same denominator. 5-3 equals 2 and 3/4-1/4 equals 2/4. So it should be 2 2/4, then I simplify it and get 2 1/2.

7 2/3 + 2 1/5 is a little more complicated. I first have to find it's common denominator which is 15. Next you rewrite the question to 7 10/15+ 2 3/15.

It should equal 9 13/15 when you add it.

Hope this helps!
