RATIO
A recipe calls for a ratio of sugar to flour to be 5 : 1. If you used 35 grams of sugar, how many grams of flour would you need to use?
- Write the ratio into a fraction form
[tex] \frac{sugar}{flour} = \frac{5}{1} \\ [/tex]
- If the you used 35 grams of sugar, what would be the flour? Find the multiple of 5 that is 35 then what is the factor.
[tex]35 \div 5 = 7[/tex]
[tex] \frac{5}{1} \times \frac{7}{7} = \frac{35}{ \sf \blue7} \\ [/tex]
Thus, the grams flour will be used when 35 of the sugar is used is 7 grams. This can be written as
35 : 7
