10/12 = 2*5 / 2*6 = 5/6
15/18 = 3*5 /3*6 = 5/6
25/30 = 5*5 /5*6 = 5/6

But what's the 13/14 :(. You can't simplify it to 5/6 or something else.

10/12=5/6 (Divide numerator and denominator by 2)

13/14=13/14 (Not equivalent to the ratio 5/6)

15/18=5/6 (Divide numerator and denominator by 3)

25/30=5/6 (Divide numerator and denominator by 5)

The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions

s344n2d4d5 [400]

Two expressions each represent the sale price of the item are:

Expression B : 0.8p is correct

Expression D: p - 0.2p is correct

<em><u>Solution:</u></em>

The regular price of an item at a store is p dollars

The item is on sale for 20% off the regular price

Therefore,

Regular price = p dollars

Discount = 20 % of regular price

Therefore,

Discount = 20 % of p

$discount = 20 \% \times p\\\\discount = \frac{20}{100} \times p = 0.2 \times p\\\\discount = 0.2p$

Sale price = Regular price - discount price

Sale price = p - 0.2p

Thus Expression D: p - 0.2p is correct

On solving, sale price = p - 0.2p

Sale price = 0.8p

Thus expression B : 0.8p is correct
