Question

fred is baking cookies.the recipe for oatmeal cookies calls for 120 g of sugar, while the recipe for chocolate chip cookies calls for 0.135 kg of sugar. what is the difference between the amounts of sugar needed in these recipes? chocolate chip oatmeal cookies require \boxed{} g or \boxed{} kg more sugar.

Explanation:

Step1: Convert units to be consistent (kg to g)

We know that \(1\space kg = 1000\space g\), so for the chocolate chip cookie recipe, the sugar in grams is \(0.135\times1000 = 135\space g\).

Step2: Find the difference in grams

Subtract the sugar for oatmeal cookies from chocolate chip: \(135 - 120 = 15\space g\).

Step3: Convert the difference to kg (optional, but for the second box)

Since \(1\space g=\frac{1}{1000}\space kg\), \(15\space g = 15\times\frac{1}{1000}=0.015\space kg\). Also, we see that \(135\space g>120\space g\), so chocolate chip requires more sugar.

Answer:

Chocolate chip cookies require \(15\) g or \(0.015\) kg more sugar.
