What happens when you multiply both the numerator and the denominator of a fraction by 9?

a. the new fraction has the same value as the original fraction but has 9 times as many parts.

b. the number in the numerator increases by 9.

c. the number in the denominator increases by 9.

d. nothing happens. the number of parts stays the same

Answer :

A- The new fraction has the same value as the original fraction but has 9 times as many parts.

step-by-step explanation :

When you multiply a fraction , just multiply the numerators, then the denominators, then symplify or reduce ...

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
