What are the ingredients for one-half of the recipe? 6 1/2 cups of flour, 7 teaspoons of cinnamon, 1/2 teaspoon of salt. What are the ingredients for one-half of the recipe?
take these mixed numbers first and switch them into fractions to do this take your whole number and multiply by the denominator of the fraction. In simplicity, You have 6 cups, and it takes 2 one-half cups to make one full cup, so to find out how many half cups 6 cups are, you just doo \[6*2=12=\frac{12}{2}=12(\frac{1}{2})\]
let me rephrase that \[6*\frac{2}{2}=\frac{12}{2}=12(\frac{1}{2})\]
so in other words 6 cups will make you 12 on half cups
its says i should multiply 6 1/2 and 1/2 right
not exactly you want to do this step by step 1) Take the whole number . In the first case you have 6 cups 2) Multiply this number by 1 (using the denominator of the preferred units: in this case one half cups. \[1=\frac{2}{2}\]*This has one half on the bottom. This is what we need!. but if we divide by two we need to multiply by two otherwise we'll screw it up =/ 3)This should get you your whole number in terms of onehalf cups
does this make sense?
well actallu 6 and 1/6 cups
alright so what has the denominator of 6 but is still one
aka \[1=\frac{?}{6}\]
ohok so 6/1 right
does \[1=\frac{6}{1}\]
oh wait do you mean the numerator has to be 6?
did you mean this \[1=\frac{6}{6}\]
cos im a little confused on like how it is like 6 1/6 then 7 then 1/2 cos the 1/6 is the fraction and the whole number is 6 which is included with the 1/6 fraction . hopefully that made sense
well the others are pretty simple ... so lets do those first
kk
So we have 7 teaspoons of cinnamon, and we only need half of that. If we multiply by one-half (or divide by 2) \[\frac{1}{2}*7=\frac{7}{2}\] This fraction can be simplified into a mixed number because 2 goes into seven 3 times with a remainder of 1/2 \[3+\frac{1}{2}\]
so you'll need three and one-half teaspoons of cinnamon
then for the flour?
next you need half of a half teaspoon of salt. using the same technique before, divide by 2 of multiply by 1/2. You'll get 1/4 teaspoon ... this can also be shown as this |dw:1362979712298:dw|
