Answer 3

okay to find a number between

Answer 4

you have to look at the average of both numbers

Answer 5

do you know how to find average of 2 numbers?

Answer 6

no do you add them?

Answer 7

yeah you add the numbers and divide by the total number of numbers you added

so you add 2 numbers 3/4,3/5
you divided by 2 after you add them


(3/4 + 3/5) / 2 = ?

Answer 8

\[\frac{\frac{3}{4} +\frac{3}{5} }{2}\]

Answer 9

when i added them i got 27/20 is the first part right?

Answer 10

Is it 27/40

Answer 11

now as dan815 said , divide them by 2

\(\bf \cfrac{\frac{3}{4} +\frac{3}{5} }{2}\implies \cfrac{\frac{27}{20}}{2}\implies \cfrac{\frac{27}{20}}{\frac{2}{1}}\implies \cfrac{27}{20}\cdot \cfrac{1}{2}\)

Answer 12

recall that \(\bf \cfrac{\frac{a}{b}}{\frac{c}{{\color{blue}{ d}}}}\implies \cfrac{a}{b}\cdot \cfrac{{\color{blue}{ d}}}{c}\)

Answer 13

would it be 2 7/10

Answer 14

\(\bf \cfrac{\frac{27}{20}}{\frac{2}{1}}\implies \cfrac{27}{20}\cdot \cfrac{1}{2}\implies \cfrac{27\cdot 1}{20\cdot 2}\)

Answer 15

Oh so it would be 27/40
