Answer:

Sadie's family car is more fuel efficient.

Step-by-step explanation:

Given;

Sadie's family car rating, S = 42 miles per gallon

Nanette's family car rating, N = 6 liters per 100 km

Sadie's family car rating, in liters per 100 km

= \frac{42 \ miles}{gallon} *\frac{1.609 \ km}{1 \ mile}*\frac{1 \ gallon}{3.79 \ liters} \\\\ = (\frac{42*1.609}{3.79} )\frac{km}{liter}\\\\ = (\frac{3.79}{42*1.609} )\frac{liter}{km}\\\\=(\frac{3.79}{42*1.609} )(\frac{100}{100}) \frac{liter}{km}\\\\= (\frac{3.79*100}{42*1.609} )(\frac{1}{100}) \frac{liter}{km}\\\\= (\frac{3.79*100}{42*1.609} ) \frac{liter}{100\ km}\\\\= 5.61 (\frac{liter}{100\ km})\\\\= \frac{5.61 \ liters}{100 \ km}

Also, Nanette's family car rating, in liters per 100 km = 6 liters / 100km.

Thus, Sadie's family car uses lesser fuel, because of this Sadie's family car is more fuel efficient.

1/2 of lla's workspace is covered in paper.1/3 of the paper is covered in yellow sticky notes.What fraction of lla's workspace i
Blababa [14]

Answer:

\frac{1}{6}

Step-by-step explanation:

We have been given that 1/2 of Ila's work-space is covered in paper.1/3 of the paper is covered in yellow sticky notes.

First of all, we will draw a model to represent our given information as shown in the attached image.

To find the fraction of Ila's work-space that is covered in yellow sticky notes, we need to find 1/3 of 1/2 as:

\text{Ila's work-space that is covered in yellow sticky notes}=\frac{1}{2}\times \frac{1}{3}

\text{Ila's work-space that is covered in yellow sticky notes}=\frac{1}{2\times 3}

\text{Ila's work-space that is covered in yellow sticky notes}=\frac{1}{6}

Therefore, \frac{1}{6} of Ila's work-space is covered in yellow sticky notes.
