heey, welcome to my wiki page. (: ♥ !  our class has been working on some great things in math, like reducing and cros multiplying(: 1. In Alberta: What is the difference between these temperatures.
 * The lowest temperature ever recorded was -61.1 C at Fort Vermillion in 1911.
 * The highest temperature was 43.3 C at Bassano Dams in 1931.

Explain on your own page how to work through this question. 1. 43.3 - (-61.1)= 43 + 61.1= 104.1

When subtracting a negative, you change it to a positive, and add it.

2. A mistake was made in each solution. Identify the line in which the mistake was made, and give the correct solution.

a) 1/3+4/3 x (-1/2) b) 5/3 x (-1/2) c) __5x(-1)__ 3x2

d) =-5/6

The mistake was made in a) because they added before they multiplied. It should be:

1/3+__4/3x (-1/2) 1/3__+ (-4/6) __2/6 - 4/6 -2/6__

-1/3

3. Write a set of rules in your own words that describes how to convert: Put it over the last place in the decimal. So if its .555, the last decimal place is the thousandths, so it's 555/1000, then reduce. Divide the numerator by the denominator. Divide the numerator by the denominator, and multiply by 100. Put the percent over 100, and reduce. Times the decimal by 100. Put the percent over 100, then reduce.
