Solve? 4/5y+2=6
\[\frac 4 5 y+2=6\] Subtract both sides by 2, what would you get? \[\frac 4 5 y +2- 2= 6-2\]
4/5 y= 4?
Yes, good :D Now multiply both sides by 5
how do i multiply a fraction by 5?
\[\frac 4 5 y= 4\] \[(\frac 4 5 \times 5 ) y= 4\times 5\] \[(\frac 4 {\cancel 5} \times \cancel 5 ) y= 4\times 5\] \[4y=4\times 5\] Do you get this?
@thatgirl666 ????
Not really so the answer is 20?
Nevermind. i then divide by 4 and it equals 5
Yeah, let me explain you the multiplication of fractions
Ok
Suppose you have the fraction \[\frac a b \] You need to multiply by a no. say c \[\frac ab \times c=\frac{a\times b}c\] If you had to multiply by 1/c \[\frac ab \times \frac 1 c=\frac a {b\times c}\] here \[a \ne b \ne c\] Do you get this?
Yes i do now Thank you
If you multiply a/b by b, what would you get?
\[\frac a b \times b= ???\]
c
We don't even have c in the expression \[\frac 2 4 \times 4=???\]
