Answer:

Step-by-step explanation:

There are 2 ways of looking at this problem

Method A

100% of the price is 598.00

75% of the price is x

So set up a proportion

100/75 = 598/x Cross Multiply

100x = 75 * 598 Simplify the right

100x = 44850 Divide both sides by 100

100x/100 = 44850/100

x = 448.50

Method Two

The other way is just to take 25% from 598

598 * 25/100 = 149.5

That's the amount of the reduction

598 - 149.5

448.5

Both answers work. You have to choose.

Which of the following expressions are equivalent to \left(9\dfrac{7}{8} + 2\dfrac{4}{5}\right)-\dfrac{1}{2}(9 87 +2 54 )− 21

Answer:

$12\dfrac{7}{40}$

Step-by-step explanation:

The given expression is

$\left(9\dfrac{7}{8} + 2\dfrac{4}{5}\right)-\dfrac{1}{2}$

We need to find the simplified form of the given expression.

It can be rewritten as

$\left(9+\dfrac{7}{8} + 2+\dfrac{4}{5}\right)-\dfrac{1}{2}$

Combine integers and fractions separately.

$(9+2)+(\dfrac{7}{8}+\dfrac{4}{5}-\dfrac{1}{2})$

Taking LCM we get

$11+\dfrac{35+32-20}{40}$

$11+\dfrac{47}{40}$

In can be written as

$11+\dfrac{40+7}{40}$

$11+1+\dfrac{7}{40}$

$12+\dfrac{7}{40}$

$12\dfrac{7}{40}$

Therefore, the expression $12\dfrac{7}{40}$ is equivalent to the given expression.
