For 6 b and d and c

#

For 7 c and d

slender magnet
#

you x across

#

then for dividing you keep the first fraction, change the second one and flip it

#

so like for example for multiplying if its like 1/2 x 3/4

#

you do 1 x 3 = 3

#

2 x 4 = 8

#

so its 3/8

#

and then for the dividing one

#

if you are doing 1/2 divided by 3/4

#

its the same as doing

#

1/2 x 4/3

#

the reciprocal

#

and then u just do the same thing

#

the negative signs dont really make a difference

#

its just basic negative numbers

#

so like 2 negatives make a positive

fervent grove
#

wait is this 6b?

slender magnet
#

oh

fervent grove
#

Or 6d

#

Which question

slender magnet
#

it was just a general overview of fractions

#

so u understand

fervent grove
#

oh okay

fervent grove
slender magnet
#

multiply

fervent grove
#

ah

slender magnet
#

like u multiply the numerators together

#

and the denominators

fervent grove
#

yeah I get it

sullen orbit
#

if its times just times the top and bottom, if its divide then flip the second fraction and times the top and bottom

fervent grove
#

The negative sign really confused me

#

Does it make the whole fraction a negative?

sullen orbit
#

one negative makes a negative

#

2 negatives make a positive

#

when multiplying or dividing

fervent grove
#

Yeah but like

#

For example look at b

#

The negative sign is in the middle of the fraction

#

not literally in the middle

#

does that make it -3 over -10

sullen orbit
#

yeah that just means the top is negative its means the same as if the negative sign were next to the 3

fervent grove
#

So it’s -3 and - 10

sullen orbit
#

no

#

-3/10

fervent grove
#

o

#

so only the numerator is negative

#

numerator is the top right

#

I can’t remember

#

it is

sullen orbit
#

yeah

fervent grove
#

so if it were d

#

then it would be -4 * -15

#

So it would be 60

#

Over 144

sullen orbit
#

yep

fervent grove
#

For 7d when I change

#

It becomes

#

-5 over 12 * - 2 over 5?

sullen orbit
#

no

#

-5/12 * -5/2

#

you're dividing so

#

you have to flip the 2nd fraction and then change the sign

fervent grove
#

oh yeah my bad

#

forgot about that part

#

was wondering if the minus would stay

sullen orbit
#

yeah it does

fervent grove
#

I should’ve came here sooner
