find the multiplicative inverse of 3/2? explain. OpenStudy (anonymous):

is it -3/2? TheSmartOne (thesmartone):

The multiplicative inverse of a fraction a/b is b/a. TheSmartOne (thesmartone):

So what do you think is the inverse now? TheSmartOne (thesmartone):

@mcnabkt OpenStudy (anonymous):

hmmm OpenStudy (anonymous):

im still confused TheSmartOne (thesmartone):

$\frac{ a }{ b }=\frac{ 3 }{ 2 }$ $\frac{ b }{ a }=\frac{ ? }{ ? }$ TheSmartOne (thesmartone):

Just switch the numbers OpenStudy (anonymous):

ohh 2/3 TheSmartOne (thesmartone):

$\frac{ a }{ b } \times \frac{ b }{ a }=1$ and $\frac{ 3 }{ 2 }\times \frac{ ? }{ ? }=1$ OpenStudy (anonymous):

1/2? TheSmartOne (thesmartone):

The number and its multiplicative inverse always multiply together to equal 1 TheSmartOne (thesmartone):

$\frac{ 3 }{ 2 }\times \frac{ 2 }{ 3 }=1$ OpenStudy (anonymous):

okay well what about the multiplicative inverse for 1/13? would it be 13/1? TheSmartOne (thesmartone):

Exactly.. Also remember any number is the same thing as over one TheSmartOne (thesmartone):

For example$5=\frac{ 5 }{ 1 }$ OpenStudy (anonymous):

so i put 13/1 for the answer? TheSmartOne (thesmartone):

Or you can just put 13 OpenStudy (anonymous):

oh i can lol OpenStudy (anonymous):

uhmm 4/17 would be.... 2? TheSmartOne (thesmartone):

17/4 not 2 TheSmartOne (thesmartone):

remember the reciprocal of the number is its multiplicative inverse OpenStudy (anonymous):

ughh well you just said or you can.. nvm different problem LOL so i just switch the numerator and denominator? TheSmartOne (thesmartone):

yes TheSmartOne (thesmartone):

that is what a reciprocal is OpenStudy (anonymous):

ohh okay well i need help with a couple more OpenStudy (anonymous):

what about multiplicative inverse of a fraction? wait were we just going over this topic? TheSmartOne (thesmartone):

yes OpenStudy (anonymous):

oh okay see i told you its very hard of me understanding lol TheSmartOne (thesmartone):

For the multiplicative inverse of a number such as 5 imagine it as 5/1 and then its multiplicative inverse is 1/5 OpenStudy (anonymous):

OH OpenStudy (anonymous):

hold on i got a few more OpenStudy (anonymous):

i got 10 out of 10 TheSmartOne (thesmartone):

Hooray. OpenStudy (anonymous):

lol i was surprised OpenStudy (anonymous):

do you understand product of fractions? TheSmartOne (thesmartone):

yes OpenStudy (anonymous):

okay good cause thats what im doing now OpenStudy (anonymous):

how are you so smart? and what GPA do you have lol OpenStudy (anonymous):

okay so 2/7 x 1/3 would be 2/21? TheSmartOne (thesmartone):

Yup.. TheSmartOne (thesmartone):

multiplication in fractions$\frac{ a }{ b }\times \frac{ x }{ y }=\frac{ ax }{ by }$ OpenStudy (anonymous):

what about -1/4x (-3/7)? would it be -3/28? TheSmartOne (thesmartone):

$\frac{ -1 }{ 4 }\times \frac{ -3 }{7 }=\frac{ -1\times-3 }{ 4\times7 }=\frac{ 3 }{ 28 }$ OpenStudy (anonymous):

yay i was right TheSmartOne (thesmartone):

No you put -3/28 not 3/28 OpenStudy (anonymous):

what about 2 1/4 x 1 3/8? i got 2 3/32 and it was wrong and i put 3/28 and got it right lol idk my class thing is a little weird it says its wrong when its right and right when its wrong TheSmartOne (thesmartone):

$2 \frac{ 1 }{ 4}=\frac{ 9 }{ 4 }$ $1 \frac{ 3 }{ 8}=\frac{ 11 }{ 8 }$ $\frac{ 9 }{ 4 }\times \frac{ 11 }{ 8 }=\frac{ 9\times11 }{ 4 \times8 }=\frac{ 99 }{ 32 }$ OpenStudy (anonymous):

ohh i guess i forgot to work it out OpenStudy (anonymous):

i dont usually work my problems out like that but im supposed to OpenStudy (anonymous):

- 1/6 x (- 3/4) how is -3/24 wrong? TheSmartOne (thesmartone):

$\frac{ -1 }{ 6 }\times \frac{ -3 }{ 4 }=\frac{ -1\times-3 }{ 6\times4 }=\frac{ 3 }{ 24 }=\frac{ 1 }{ 8 }$ OpenStudy (anonymous):

oh i forgot to simplify i guess TheSmartOne (thesmartone):

Also the - sign TheSmartOne (thesmartone):

$\frac{ 3 }{ 24}\neq \frac{ -3 }{ 24 }$ OpenStudy (anonymous):

-2 2/3 x 4 2/5 would be... -8 4/15? then i simplify it and i get
