will medal please help....
4/11 times 5/4
i got this dont know what to do
multiply straight across.
what is 3/3 , 2/2 , x/x would be ??
i got 880/44 can't convert it to a mixed i just dont know how to do this the options are 4/11 5/11 or 6/11
do 4 times 5 and 11 times 4 and simplify
\[\large\rm \frac{ 4 }{ 11 } \cdot \frac{5}{4}\] try to cancel out something if you can. make it easy
what nnesha
k 20/44 now what
simplify by dividing each one by 4
here is an example \[\huge\rm \frac{ x }{ \cancel{y} } \cdot \frac{\cancel{y}}{z}\] you can cancel out the y first and then multiply them
so...?
divide each one of the values in your fraction by 4.
\[\large\rm \frac{ 4 }{ 11 } \cdot \frac{5}{4}\] can you cancel out something before multiplication ?
4 and 4 what does that do nnesha
\[\frac{ 20 }{ 44} \div \frac{ \div4 }{\div4 } = \frac{ ? }{ ? }\]
\[\large\rm \frac{ \cancel{4} }{ 11 } \cdot \frac{5}{\cancel{4}}\] \[\frac{ 1 }{ 11 } \cdot \frac{5}{1}\] now just multip.y numerator by numerator and denominator by denominator
i know what the answer is but it's still confusing because they dont have the same denominator until you multiply the 11 by the 1
but whatever thanks
you don't need to have the same denominator for multiplication.
common denominator is necessary when we add or subtract fractions
ohhhh ok thx bbg
\[\frac{ 1 }{ 11 } \cdot \frac{5}{1}\] now just multiply \[\frac{ 1 \cdot 5 }{ 11 \cdot 1 } =\frac{5}{11}\] that's it
