Subtract: 4/5  ₋₋  2/3 (in pictorial)

4/5 - 2/3

LCM of denominators= 15

4/5 or 12/15

2/3 or 10/15

12/15- 10/15= 2/15

In explanation

Step-by-step explanation:

So first were going to gave to get the denominators the same because 1 is 5 and other is 3.

How can we do that?

Were going to times 5 and 3 to their factor which is 15,how many rimes does it take to get to 15 from 5?

It takes 3 5 x 3 =15  

and then it takes 5 times for 3 to get to 15 so 3 x 5=15

So now that our denominators are the same were going to have to change our numerators for the first one 4/15 since 5 was times 3 times we have to also times 4 3 times so there fraction is now 12/15

And for the second one we times 2 5 times to make 10 because 2 x 5=10.

So now we are adding 12/15 + 10/15.

So lets now add the numerators not denominators because that you don't add so what's 12 + 10.

12 + 10=22 and now our fraction is an improper fraction meaning our numerator is bigger than our denominator(so we have to change that)

To change that we can have a whole number meaning can we have a whole yes because for our fraction if our numerator is bigger than 15 that means we get 1 whole.

Our fraction is 22 meaning we can have 1 whole plus extra so were taking 15 from 22 to get 1 whole.

So what is 22 - 15

22 - 15= a total of 7 so now our fraction turns into 1 and 7/15 and that's our answer.

Hope this helps have a great day:)
