10. What is the solution to the rational equation 4x/3 divided by 1/3=5?

Parth (parthkohli):

\(\Large \color{MidnightBlue}{\rightarrow {4x \over 3} \div {1 \over 3} \text{can be said as} {4x \over 3} * {3 \over 1} }\)

OpenStudy (anonymous):

so = just 4

Parth (parthkohli):

\(\Large \color{MidnightBlue}{\rightarrow 4x = 5 }\) \(\Large \color{MidnightBlue}{\rightarrow x = ? }\)

OpenStudy (ash2326):

my bad:P @ParthKohli has explained it properly

OpenStudy (anonymous):

1/6?

Parth (parthkohli):

When we divide a fraction by a fraction, then we multiply the fraction by the other's reciprocal.

Parth (parthkohli):

@nyan21 Nyan cat, don't guess lol

Parth (parthkohli):

Divide both sides by 4.

i not guessing this is what im getting from the choices im choin the closest lol

OpenStudy (anonymous):

so itd by 1.25 but thats not a choice

Parth (parthkohli):

\(\Large \color{MidnightBlue}{\rightarrow {4x \over 4} = {5 \over 4} }\)

OpenStudy (anonymous):

4?

Parth (parthkohli):

x = 1.25 or 5/4

Parth (parthkohli):

Or \(1{1 \over 4}\)
