Answer 21

I'm confused.Where did 1/(7*2) come from?

Answer 22

@jada1701877 : I misread what you'd typed. The middle fraction is 1/(7*2), not 1/(7^2) as I had first read it.

You have 4 (a whole number), 2/(7*2) (a fraction with denominator 14), and 1/5 (a fraction with denom. 5). Note that 2/(7*2) reduces to 1/7. Sorry: I had this wrong in my last post.

Answer 23

Then add up: 4 + (1/7 + 1/5).

Answer 24

You were right all along: And for 35 I just thought of what is the lcd and it's 35

Again, my apologies.

Answer 25

Ohh it's alright. We all make mistakes but thanks for the time and for helping me anyways :)
