1/2+4/10 for example
in a decimal way: 1/2+4/10 = 0.5+0.4. add those two and it is 0.9
in a fraction: 1/2+4/10 = 5/10+4/10. add the numerators, which is 9, and you keep the denominator so it is 9/10
What you meant was the "commutative" property.
So we can say that when adding:
<em>"<u>Commutative</u> means that the order does not make any difference in the result."</em>
Example:
5 + 6 = 6 + 5
a + b = b + a
The commutative property does not hold for subtraction.
Example:
4 - 1 ≠ 1 - 4
a - b ≠ b - a
Ok, now does the commutative property hold true for multiplication?
2 x 3 = 3 x 2
2 x 3 x 4 = 4 x 3 x 2
Yes.
What about division?
12 ÷ 4 ≠ 4 ÷ 12
The commutative property does not hold for division.
100*1.2828...= 128.28282828..( so on..)
100x=128.28
then you do 100x - x = 128.2828...- 1.2828..
then we subtract the .282828... part
99x = 127
then divide boths sides by 99 and then x=127/99
Answer:
6/2
I'm so good at disss yeaayyyyy
