Question

5/12 divided 1/2 X 7/6= 35/144 is it right or where did i go wrong

Answer 1

Are you asking if
\[\frac{5}{12} \div \frac{1}{2} \times \frac{7}{6} = \frac{35}{144}\]

Answer 2

yes

Answer 3

well in the problem i have their arent parentheses, just reads to simplify

Answer 4

Okay

Answer 5

So that means, all you have to do is flip the 1/2:
\[\frac{5}{12} \times \frac{2}{1} \times \frac{7}{6}\]

Answer 6

Now you can just multiply the numerators then the denominators.

Answer 7

ok il do that

Answer 8

35/36

Answer 9

Actually, If you write it like this:

\[\frac{(5)(2)(7)}{(12)(6)}\]
You'll realize that you can cancel 2 and 6

Answer 10

Good job

Answer 11

\[\frac{(5)(7)}{(12)(3)} = \frac{35}{36}\]

Answer 12

Remember that when you're dividing two fractions you have to flip the second fraction according to the reciprocal rule.

Answer 13

ok thanks for that i was confused as to why you flipped it/... thank u

Answer 15

when it is a for example 36/84 if you cant divide after that you find the lcm to get an answer ? this question also refers to when dividing

Answer 16

You probably forgot to reduce factors of one before multiplying

Answer 17

look 4/3 divided by 9/28 ( i already flipped the 2nd part) = 36/84 lcm is 12 my final answer would be 3/7

Answer 18

I would do it this way:

\[\frac{4}{3} \div\frac{9}{28} = \frac{4}{3} \times \frac{28}{9} = \frac{(4)(4)(7)}{(3)(3)(3)} = \]


Doing it this way we see that nothing cancels. So we have to multiply it all out.

Answer 19

ok got it

Answer 20

However, after multiplying, you'll have an improper fraction.

Answer 21

You'll have to re-write it as a whole number plus a fraction
