total of 0.17+0.204+2.3 also subtract 0.03-0.021 & 0.34 times 9=?divide 3.7 by 1.1 rounded to nearest hundred?

Answer 1

1) 0.17
+ 0.204
2.3
-----------
2.6 7 4


2) 0.34
x 9
--------
3.06

3) 0.030
- 0.021
----------
0.009

substract 0.009 = - 0.009


4) 2.674
+ 3.060
----------
5.734

5.734
- 0.009
----------
5.725

5) 5.725 = ?/(3.7 x 1.1)


3.3
x 1.1
----------
3 3
+ 33
----------------
3.63


5.725
x 3.630
-------------
0000
+ 17175
34350
17175
------------------
20.781750

Final answer : 20.78

Answer 2

Without using a calculator (which is cheating), Line them up vertically so the decimal points are above each other like so:

0.170
0.204
2.300
=====
2.674

Then add just like you always did for addition. Note that I added zeros to the end so they were all the same length.
This is not necessary as long as you understand that the
value is zero. I did it for clarity. Now,
0.030
-0.021
=====
0.009
Same as normal subtraction. Borrow a 1 from the 3 to get
10 and subtract the 1.

0.34 * 9 = 3.06 Just multiply like normal. Then remember that there were 2 decimals so there needs to be 2 decimals in the answer.

3.7/1.1 = 3.36363636 and so forth. Now round it to 100ths.
10ths = 1 decimal place (3.4)
100ths = 2 decimal places (3.36)
1000ths = 3 decimal places (3.364) and so forth.

Answer 3

Arithmetically,
0.17 + 0.204 + 2.3 = 2.674
0.03 - 0.021 = 0.009
0.34 * 9 = 3.06
3.7 / 1.1 = 3.363636363636363636363636 . . .
Practically,
0.17 + 0.204 + 2.3 = 2.7
0.03 - 0.021 = 0.009
0.34 * 9 = 3.1
3.7 / 1.1 = 3.4
3.7 by 1.1 rounded to nearest hundred = 0
3.7 by 1.1 rounded to nearest hundredth = 3.36

Answer 4

(1) 2.67
(2).01
(3)3.06
(4) 3.36
