Tonie's Math Question

The question I was given:


To solve: First, I multiplied 8.2m by 4.5m and I got 36.90 or 36.9

Then I multiplied 36.9 by 2/5. But before I multiplied both numbers, I converted 2/5 into decimals to make it easier.


After, I multiplied 36.9 by 0.4 and I got 14.76



Lastly, I found the square root of 14.76 which equals to 3.8



S.S. The side lengths of the rug is 3.8m

Chapter 2.3: Question #9

The question I was given:



Step 1:
To find 1/3 of 39, first you have to divide 39 by the denominator (3). So 39 divided by 3 is equals to 13. After, you multiply 13 by the numerator (1). 13x1=13. Then, you subtract 39 to 13 which gets you 26.



Step 2:
To find 1/4 of 26, first you divide 26 by the denominator of 1/4 which is 4. So 26 divided by 4 is equals to 6.5. Then, you multiply 6.5 by 1 which gets you 6.5. So 1/4 of 26 is 6.5. To find the remaining debt, you subtract 26 to 6.5 and it gets to 19.5.
