Let's solve the problem step-by-step to determine what percent of the flour is left after Katie used some for baking.
1. Identify the fraction of flour used:
Katie used [tex]\(\frac{3}{8}\)[/tex] of the flour.
2. Convert the used flour fraction to a percentage:
To determine how much flour Katie has used in terms of percentage, we multiply the fraction by 100:
[tex]\[
\frac{3}{8} \times 100 = 37.5\%
\][/tex]
So, Katie used 37.5% of the flour.
3. Calculate the percentage of flour left:
Katie started with 100% of the flour and used 37.5%. The percentage left is:
[tex]\[
100\% - 37.5\% = 62.5\%
\][/tex]
Therefore, after using [tex]\(\frac{3}{8}\)[/tex] of the flour to bake, Katie has 62.5% of the flour left.
