|dw:1617122658489:dw| can you add it up first to find the sides of the larger rectangle? What is 1/3 + 1/3 and what is 1/2 + 1/2 + 1/2

slice:

1.5

AZ:

what about 1/3 + 1/3 =

AZ:

1.5 is the same thing as 3/2 by the way

slice:

idk

AZ:

add the fractions when the denominator (or the bottom part of the fraction) is the same you can just add the numbers in the numerator so \(\dfrac{a}{c} + \dfrac{b}{c} = \dfrac{a+b}{c}\)

AZ:

so basically 1/3 + 1/3 = ??

slice:

2/3

slice:

hello>

AZ:

yes!! so now we have the two sides 2/3 and 3/2 what do you get when you multiply it?

slice:

2 1/6

AZ:

no remember when you're multiply, you multiply the numerator together and the denominators together so \(\dfrac{a}{b} \times \dfrac{c}{d} = \dfrac{a\times b}{c\times d}\)

AZ:

so what is \(\dfrac{2}{3} \times \dfrac{3}{2} = \)

slice:

6

AZ:

the numerator is 6 what about the bottom part

slice:

6

AZ:

so what is 6/6 =

slice:

6

slice:

1

AZ:

now you got it! when you divide a number by itself, you get 1

slice:

thank you

AZ:
