Number of the Day #21

Use any two digits to make a proper fraction

eg. 7634.29

For it to be a proper fraction, the numerator (top number) always has to be smaller than the denominator (bottom number)

Number of the Day Question #20

20. Make a fraction using the thousands place digit as the denominator, and the tenths place digit as the numerator.

The denominator is the bottom number of a fraction, the numerator is the top number.

Doing number 20 is easy like cake, you just have to make the thousands place the denominator, and the tenths place the numerator.

2. Min had a mark of 26 out of 31 on a science test. That same day, his sister got a mark of 45 out of 52 on a math test. Explain how to find out who got the better mark.

Min: 26 ÷ 31 = 0.83 = 83%
Sister: 45 ÷ 52 = 0.86 = 86%
Min's got 26 out of 31, so you do 26 ÷ 31.
Min's sister got 45 out of 52, so you do 45 ÷ 52
Min's sister got a higher mark!

Math Textbook #8

So, today I did number 8
"How could you mentally find 40% of 180?"
Here's how I did it:
Really easy, eh?

nov.15/11 textbook question

6. arrange the following expressions in ascendingorder
aaa_ ilovemathilovemath99_
a 0.7, 76%,3/4 3/4<76%<0.7

Textbook Page 138, Number 8 (Bar Notation)

So if you calculate 1 divided by 3 or something of that sort you'll probably get something like this for most calculators: 0.3333333333333333333333333333333333333333...

If that is on a test that answer would be far too long, so we need some other way to write that answer down (and because mathematicians are super lazy.)

That's why the bar notation is invented

Okay here's the actual homework:

Page 137 #5

Convert each fraction into a decimal
a. 13 over 25= 0.5
13÷25= 052 round to the nearest tenth = 0.5
b. 107 over 215= 0.50
107÷215= 0.49766744 round to the nearest thousandth = 05.50
c. 43 over 50= 0.9
43÷50= 0.86 round to the nearest tenth
d. 197 over 289= 0.6816608
197÷289= 0.680 round to the nearest thousandth

7. A baseball player’s batting average is the
ratio of number of hits to times at bat. It is
usually expressed as a decimal number.

Number of hits
Batting average= ___________

Times at bat

PLAYER TIMES AT BAT HITS
A 605 194
B 624 197

a) What is the batting average for each
player? Round each answer to the
nearest thousandth.
A= 3.1185567-3.119
B= 3.19675126-3.168

b) Which player had a better batting
average for the season? Justify your
response.
= Player B, because he had more hits
than Player A.

10) Change each fraction to a repeating decimal.
Then use bar notation to show the repeating part.

How I did the fraction part is divided the numerator into the denominator.
So when I divided it went into a repeating decimal.
The repeating decimal is too long instead of writing all of the numbers down put a bar notation on top on a number that is always repeating.
I did number 11 on page 138.
