Question

4/5 y - 1/2 y = 3
help please!!!

Answer 1

\[\frac{ 4 }{ 5 } y - \frac{ 1 }{ 2 } y = 3\]

Answer 2

\[-\frac{ 7 }{ 2 } \div \frac{ 3 }{ 5 }\] I don't remember how to do this....

Answer 3

multiply everything by a common denominator to get rid of the fractions.
In this case 10
\[10\frac{ 4 }{ 5 }y - (10)\frac{ 1 }{ 2 }y= 10(3)\]

\[\frac{ 40 }{ 5 }y-\frac{ 10 }{ 2 }y=30\]
now simplify and solve

Answer 4

on the 2nd one change it to multiplication by taking the reciprocal of the 2nd fraction

\[\frac{ -7 }{ 2 }\div \frac{ 3 }{ 5 }=\frac{ -7 }{ 2 }\times \frac{ 5 }{ 3 }\]

to multiply fractions....just multiply straight across

-7 * 5
------ = ------
2*3

Answer 5

make sense?

Answer 6

The first one doesn't, but the second one does

Answer 7

40/5y - 10/2 y = 30

8y - 5y = 30

3y = 30

y = 10
