First try to get the same denominator for both of the parts i have marked so that you can subtract the fractions

#

Yes I've done that. It's hard to make a picture with laptop.

#

Above it's 18 and underneath 35

#

After that I multiplied 1x3 6x3 for above. Underneath 7x2 and 2x5

#

Ok now you just need to divide the 2 fractions and to do that

#

You Will essentially flip the denominator and muliply it with the numerator

#

Wait

half anchor
#

Okay, thanks in advance.

analog perch
#

So one example could be this

#

you flip the denominator

#

And muliply with the numerator

#

That always works with fractions

half anchor
#

Yes thanks. I knew.

I have -27/18 and -4/35

#

So -27/18 * 35/-4

analog perch
#

yes

half anchor
#

My outcome was 1295/72

#

And when simplify it wasn't the same as in the answers

#

the answer book says: 105/8

#

Wait let me try

half anchor
#

Sure, thank u.

analog perch
#

But

#

If you muliply the numerator so -27 and 35

#

It should be 945 not 1295

OH WOW i'm so sorry

#

Im so stupid I swear

#

to multiply 27 x 35 I broke it down.
So:
10 = 350
20 = 700
and added 7 = 245. And idk why but added all these. So instead of 27 I did 37

#

Nah that happens to everyone
