Strike441 [17]

Answer:

\frac{4}{9}\div 2=\frac{2}{9}

Step-by-step explanation:

We want to simplify;

\frac{4}{9}\div 2

We can rewrite to get;

\frac{4}{9}\div \frac{2}{1}

We multiply the first fraction by the multiplicative inverse of the second fraction to get;

\frac{4}{9}\times \frac{1}{2}

This gives us;

\frac{4\times1}{9\times2}

Simplify to get;

\frac{2\times1}{9\times1}

Multiply;

=\frac{2}{9}

Help will mark brainiest
Kitty [74]

Answer:

original price =148.57

Step-by-step explanation:

The original price * discount  is the markdown

original price - discount = sale price

original price - original price * discount = sale price

Factor out the original price

original price (1-discount) = sale price

We know the discount is 65% and the sale price is 52

original price (1-.65) = 52

original price (.35) = 52

Divide by .35 on each side

original price (.35)/.35 = 52/.35

original price =148.57
