\[\frac ab\times\frac cd=\frac{a\times c}{b\times d}\]
OpenStudy (abb0t):
\[\frac{ 3 }{ 2 } \times \frac{ 1}{ 2 } = \frac{ 3 \times 1 }{ 2 \times 2 }\]
OpenStudy (zugzwang):
^What he said...
I actually find multiplying fractions a lot less tricky than adding or subtracting them.
OpenStudy (anonymous):
And if you invert it then you are dividing :D
OpenStudy (zugzwang):
Provided you have mastered reducing fractions to lowest terms.

*the second fraction
OpenStudy (anonymous):
okay so the answer should be 3/6
OpenStudy (anonymous):
Mmm this is true
OpenStudy (zugzwang):
Well, it must be 3/6...
But you can do better than that~
Lowest terms...?
OpenStudy (anonymous):
1/2

Wait a sec. what was the question to which your answer was 3/6
?
OpenStudy (anonymous):
wait so any time the number is odd i the lowest term always gonna be 1
OpenStudy (anonymous):
3/2 x 1/3
OpenStudy (anonymous):
my answer was 3/6 then you said lowest terms so i said 1/2 was I right
OpenStudy (zugzwang):
Yes. Let's have another one:
\[\frac{4}{3}\times\frac{9}{4}\]

36/12
OpenStudy (zugzwang):
Yes... continue...
OpenStudy (anonymous):
but how would i continue if both of there lowest terms are 2
OpenStudy (zugzwang):
2? How do you figure 2?
OpenStudy (anonymous):
well if you do 36>18>9>3>1
12>6>>2 oh i see

OpenStudy (anonymous):
so it be 1/2 right
OpenStudy (zugzwang):
NO...
Remember that in the end, fractions are just compact division:
\[\large \frac{a}{b}=a \div b\]
So what is 36 divided by 12?
OpenStudy (anonymous):
3
OpenStudy (zugzwang):
And there is your answer.
OpenStudy (anonymous):
so the answer is flat out 3

Yes. Remember that this can happen. Anyway, a whole number is technically a fraction with a denominator of 1, in lowest terms.
OpenStudy (anonymous):
so if i wanted to make it into fraction form id just 3/1
OpenStudy (anonymous):
?
OpenStudy (unklerhaukus):
yeah
