Suppose you are asked to find the area of a rectangle that is 2.1-cmcm wide by 5.6-cmcm long. Your calculator answer would be 11

Jlenok [28]

Answer:

12 square cm correct to 2 significant figures

Step-by-step explanation:

Area of a Rectangle = L X B = 2.1 X 5.6 = 11.76 square cm

To round your result to 2 significant figure, we start counting from the left from the first non-zero digit.

The first two digits are 11 but because the number after is 7 (greater than 4), we round up to 12.

11.76 square cm = 12 square cm correct to 2 significant figures

Anarel [89]

Answer:

Ryo ordered $\frac{12}{5}$ of the amount of eggs his restaurant needed

Step-by-step explanation:

Let's call z the number of eggs the restaurant needs

Ryo ordered 240% of the eggs he needed. Then Ryo ordered:

$\frac{240}{100}$ z.

This fraction can be simplified by dividing by 10 in the numerator and denominator.

Then it is:

$\frac{24}{10}$

It can be further simplified by dividing by 2 in the numerator and denominator:

$\frac{12}{5}$ z

Ryo ordered $\frac{12}{5}$ of the amount of eggs his restaurant needed
