Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Decimal and Percent

Let’s do a review on converting from decimal to percent and vice versa.

Converting from Decimal to Percent

Percent means per hundred. Twenty percent is just another way of saying "twenty out of a hundred," or twenty hundredths.

To convert from decimal to percentage, just simply multiply the decimal by 100, but remember to put the "%" sign so people know it is per 100. The easiest way to multiply by 100 is to move the decimal point two places to the right.

Example:

Convert the decimal 0.48 to percent.

Solution:

Move the decimal point two places to the right and add a percent sign: 48%. Or, multiply the decimal by 100 and add a percent sign: 0.48 x 100 = 48%

Converting from Fraction to Percent

To convert a fraction to a percentage, you must first convert the fraction to a decimal by dividing the numerator by the denominator. Then simply follow the steps for converting a decimal to a percent by moving the decimal point two places to the right (which is the same as multiplying by 100) and don’t forget the percent sign (%).

Example:

Convert the fraction 3/8 to percent.

Solution:

First convert the fraction to a decimal: 3/8 = 0.375

Then convert the decimal to a percent: 0.375 x 100 = 37.5% 

Converting from Percent to Decimal

To convert a percent to a decimal, just simply divide the percent by 100, but remember to remove the percent sign (%). Alternatively, we can remove the percent sign and move the decimal point two places to the left.

Example:

Convert 7.5% to a decimal.

Solution:

Remove the percent sign and move the decimal point two places to the left: 0.075

Or, divide the percent by 100 and remove the percent sign: 7.5% ÷ 100 = 0.075

Converting from Percent to Fraction

To convert a percent to a fraction, remove the percent sign (%) and divide the percent by 100,then reduce the fraction or move the decimal point to the right until you have only integers. (Note: If you move the decimal place to the right two digits in the numerator, you must do the same in the denominator).

Example:

Convert 7.5% to a fraction.

Solution:

Remove the percent sign and divide by 100: 7.5% = 7.5/100

Now move the decimal point to the right 1 digit:

7.5/100 = 75/1000

Finally, reduce the fraction:

75/1000 = 3/40
