Question

I need help with my fractions homework. It is 5th grade math.

Answer 1

hey =). ok so give an example problem to give me an idea of what you're struggling with

Answer 2

Well, I am Comparing and Ordering fractions, Mixed Numbers, and Decimals.

Answer 3

ok sure

Answer 4

5 1/3 and 6.7

Answer 5

right, ok

Answer 6

Can you explain it to me.

Answer 7

hahahah homeworkhelpgirl... made a new account

Answer 8

so 5 1/3 means 5 , and then 1/3 of 1

Answer 9

in decimal form, that means 5.333333333

Answer 10

Remember I am only in the 5th grade,,,,

Answer 11

sandra can you help me with regression when you're finished please?

Answer 12

but conceptually, you can see that 5 1/3 is less than six, because 5 1/3 = 5 + 1/3 (which is less than one), and 6.7 means 5 + 1.7 (which is more than one)

Answer 13

sorry briibaby, too advanced for me!

Answer 14

What?

Answer 15

another way to compare them is to turn them both into fractions

Answer 16

but let's see some other sample problems too

Answer 17

for example, what is bigger, 1/2 or 1/3?

Answer 18

1/3?

Answer 19

nope, it's just the bottom number is bigger. let me show you how to compare

Answer 20

to compare fractions, it helps to find what's called a common denominator

Answer 21

for example, if I asked you what's bigger, 1/3, or 2/3, what would you say?

Answer 22

Wait :) I have some numbers with decimals with them!

Answer 23

ok but 2/3 is bigger than 1/3, because the top number is bigger in 2/3 than 1/3 - and they're fractions out of the same overall unit (3's)

Answer 24

but go ahead and post another example with decimals

Answer 25

How do convert fractions into decimals?

Answer 26

well, it's easiest to make it so some power of 10 is on the bottom

Answer 27

for example, 1/10 = .1 , 1/100 = .01, 1/1000 = .001
The rule is, you're allowed to move the decimal one to the left with each zero that's on the bottom

Answer 28

I don't understand.

Answer 29

well, 1/10 is another way of writing "one divided by ten"

Answer 30

and when I divide by some power of 10 - for example 10, 100, 1000, 2000, all that means is moving the decimal point one to the left

Answer 31

so 1 divided by 10 is .1

Answer 32

2 divided by 10 is .2

Answer 33

I just move the point one to the left

Answer 34

multiplying by some power of 10 means I get to move the decimal point one to the right, and add a zero

Answer 35

so 1 x 10 = 10 (added one zero), 2 x 100 = 200 (I get to add two zeros), and 6.7 x 10 = 67 (I get to move the decimal point to the right)

Answer 36

so there are two ways to compare a decimal and a fraction

Answer 37

one way would be to convert the fraction to a decimal - and then compare them

Answer 38

another way would be to convert the decimal to a fraction, and then compare those fractions

Answer 39

I imagine they want you to learn the second approach

Answer 40

now to compare fractions, as I was saying earlier, you need to find what's called a "common denominator"
