Question

Please help!, it's really easy but i'm having trouble!

Answer 1

Answer:

So your answer is D.

Step-by-step explanation:

First you are going to have to convert 1 into a fraction which is 1/1

1/1 - 1/4 + 2/5

now you have to remember what ever you do to the top you have to do to the bottom of the fraction

1/1 times by 20 = 20/20

1/4 times by 5 = 5/ 20

2/5 times by 4 = 8/20

so your answer will be D

Answer 2

Answer:

20/20 - 5/20 + 8/20

Step-by-step explanation:

1 - 1/4 + 2/5

Denominator:  4 x 5 = 20

So

   1 = 1 x 20/20 = 20/20

1/4 = 1/4 x 5/5   = 5/20

2/5 = 2/5 x 4/4 =  8/20

Now you have

1 - 1/4 + 2/5 = 20/20 - 5/20 + 8/20

Answer: 20/20 - 5/20 + 8/20
