Answer:

7/20

Step-by-step explanation:

1/4+1/10

We need to get a common denominator of 20

1/4 *5/5 = 5/20

1/10 *2/2 = 2/20

5/20 + 2/20 = 7/20

Answer:

7/20

Step-by-step explanation:

First, we need to find a common denominator.

The easiest way to do this is to look at the factors of each number:

4: 1, 2, 4

10:1, 2, 5, 10

Therefore, we can conclude that 20 would be a good denominator.

\frac{1}{4} = \frac{5}{20}

\frac{1}{10} = \frac{2}{20}

5 + 2 = 7.

Thus, \frac{7}{20} is our final answer.

GamesOnly is having a “30% Off Everything!” sale. They have a PS4 on sale for $182. What was the original price?
Setler79 [48]

Answer:

original price = 260

Step-by-step explanation:

original price * percent off = discount

then subtract the discount

original price - discount = new price

so

original price - original price * percent off = new price

factor out the original price

original price( 1- percent off) = new price

original price = new price/ ( 1- percent off)


lets put in what we know

original price = 182/(1-.30)

original price = 182/(.7)

original price = 260
