Answer 1

@vils123 If you need help in a particular question or topic. Post it, We'd be glad to help:)

Answer 2

I need help with fractions

Answer 3

Ok, post any question of it

Answer 4

ok um 5/4 - 5/9

Answer 5

We have
\[\frac{5}{4}-\frac{5}{9}\]
Whenever you have to add or subtract two fractions, first notice their denominators
If they are same we can just add or subtract, else we'll try to make them same

Answer 6

Here the denominators are not same
4 and 9 . Can you tell me the LCM of 4 and 9?

Answer 7

2x2 and 3x3

Answer 8

These are just factors, tell me the LCM

Answer 9

i dnt get LCM

Answer 10

Least Common Muiltiple

Answer 11

i dont kknow how to do that

Answer 12

Okay , suppose we have to find LCM of 4 and 6
First step , write factors of 4 and 6
4=2 *2
6=2*3
LCM is the product of all the uncommon factors and the common factor (listed only once)
We can notice the common factor is 2 in 4 and 6 , 4 has one more factor 2 and 6 has 3
so
LCM is 2*2*3=12
Can you tell the LCM of 4 and 9?

Answer 13

so how would i get the lcm

Answer 14

Why don't you go to Khan academy's web site and watch the videos on fractions.

Answer 15

i want to work with tutors

Answer 16

Vils I've shown you how to find LCM, follow the same procedure to find LCM of 4 and 9

Answer 17

is the lcm 36?

Answer 18

Yeah correct:D

Answer 19

so then what

Answer 20

Now we found the LCM as 36
we have
\[\frac{5}{4}-\frac{5}{9}\]
Now LCM=>36/4=9 and 36/9=4
So
multiply first fraction's numerator and denominator by 9 and second fraction's numerator and denominator by 4
\[\frac {5\times 9} {4 \times 9}-\frac {5 \times 4}{9 \times 4}\]
We get
\[\frac{45}{36}-\frac{20}{36}\]
we now have
\[\frac{45-20}{36}\]
finally we get
\[\frac{25}{36}\]

Answer 21

what about improper and proper fractions, mixed numbers
