Answer:

y = $\frac{2}{9}$

Step-by-step explanation:

multiply $\frac{2}{3}$ by $\frac{3}{3}$ to get $\frac{6}{9}$ :

$\frac{6}{9}$ + y - $\frac{1}{9}$ = $\frac{7}{9}$

simplify:

y + $\frac{5}{9}$ = $\frac{7}{9}$

subract $\frac{5}{9}$ from both sides:

y = $\frac{2}{9}$

Which number is greater and by how much? a decreased by 50% and then increased by 50% of the result

zaharov [31]

Answer:

Let's assume the number is 100 now it is increased by 50% that means

100+ (50/100)*100

100+50=150

Now it is decreased by 25% that means

150- (25/100)*150

150–37.5=112.5

Total percentage increase ={(112.5–100)/100}*100

=12.5%
