Answer 2

subtract the two

Answer 3

these i would turn to improper fractions first, then put over common denominator

Answer 4

So, this is a problem dealing with subtracting fractions. We have to subtract

\(\color{blueviolet}{10\dfrac{2}{3}}~ -~~\color{limegreen}{8\dfrac{3}{4}}\)
Do you know the first step in subtracting fractions?

Answer 5

Finding the Common detonators?

Answer 6

no dont blow them up

Answer 7

Correct =) Do you know the common multiples of 3 and 4?

Answer 8

12

Answer 9

Oops I am sorry. I made a mistake give me a second

Answer 10

Good, so after we have found the common denominator we should have this

\(\color{blueviolet}{10\dfrac{8}{12}}~ -~~\color{limegreen}{8\dfrac{9}{12}}\)

Because 12/3 = 4, so \(\color{blueviolet}{10\dfrac{2\times4}{3\times4}}\)

And 12/4 = 3, so \(\color{limegreen}{8\dfrac{3\times3}{4\times3}}\)

Do you know how to subtract this? \(\color{blueviolet}{10\dfrac{8}{12}}~ -~~\color{limegreen}{8\dfrac{9}{12}}\)

Answer 11

Not really

Answer 12

OK so let's make these fractions improper. Do you know how to do that?

Answer 13

Yep hold on

Answer 14

OK =)

Answer 15

128/12 and 105/12

Answer 16

Hello?

Answer 17

Correct =) Sorry, so now we have All you need to do is subtract 128-105 and keep the denominator 12
