Question

Evaluating Expressions

Answer 1

\[\ 5(\frac{ x }{ y})-x\]

Answer 2

x = 6
y = 2/3

Answer 3

replace the x's in your expression with 6 and the y with 2/3
what part is tripping you up?

Answer 4

The 'y' how can a fraction be the denominator of another fraction?

Answer 5

\[\frac a{\frac bc}=a\cdot\frac cb\]

Answer 6

so dividing by a fraction is the same as multiplying by its reciprocal

Answer 7

5 * 3/2?

Answer 8

@hartnn do you understand this? What he said didn't help.

Answer 9

what he said was correct
\(\huge \frac{a}{\frac{b}{c}}=a.\frac{c}{b}\)
so now u have 5*(x/y) where x=6 , y= 2/3
so
\(\huge \frac{5}{\frac{2}{3}}6=5.\frac{3}{2}.6\)
make sense ?

Answer 10

@hartnn LaTeX note
\cdot\[\cdot\] (puts the dots in the middle ;) )

Answer 11

why do you put 5/2/3?

Answer 12

\(5 \cdot 6\)
:) thanks .

Answer 13

The 5 wasn't apart of the fraction

Answer 14

because the question had 5x/y

Answer 15

5(x/y) = 5x/y = (5x) / y

Answer 16

Yeah but that answer gives you 45

Answer 17

My teacher said the answer was 39

Answer 18

@Hero can you help?

Answer 19

No one helped you already?

Answer 20

Yes, but I don't understand why they are doing what they are doing

Answer 21

I'm trying to figure out why everyone puts 5 in the numerator but it is not like that

Answer 22

its a mixed number

Answer 23

because u are yet to subtract 6
u got 45,
45-6 = 39 ...

Answer 24

isn't 5 in numerator ?

Answer 25

In the original problem it is not

Answer 26

where is 5 according to u ?
