Help I'm really bad at math/division

I can help you all you need to do is get a phone or a tablet and look up dividing fractions calculator and hit the first one

See below

Step-by-step explanation:

The trick to dividing fractions is to keep the left fraction, but flip the numerator and denominator of the right fraction around (aka. take the reciprocal), which we multiply these fractions.

Ex: 5/9 divided by 8/9 is the same as 5/9*9/8 which is 45/72 or 5/8

1/10 divided by 1/2 is the same as 1/10*2/1 which is 2/10 or 1/5

Hopefully, this helps you figure out the last two!

step-by-step explanation:

compare

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
