Answer:
20
Step-by-step explanation:
We already have our first value 3.4 and the second value 17. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
Step 1 ---> 3.4 = 17% × Y
Step 2 ---> 3.4 = 17/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 17 we will arrive at:
Step 3 ---> Y = 3.4 × 100/17
Step 4 ---> Y = 3.4 × 100 ÷ 17
Step 5 ---> Y = 20
Finally, we have found the value of Y which is 20 and that is our answer.
<h3><u>
*You can easily calculate 3.4 is 17 percent of what number by using any regular calculator, simply enter 3.4 × 100 ÷ 17 and you will get your answer which is 20*</u></h3>

Answer:
commutative property
Explanation:
This is known as the commutative property of addition (and multiplication).
An easy way to remember the property is that the two elements commute, or exchange places, or that one element commutes from one side of the operation to the other, like a commuter (passenger) on a commuter train.
a + b = b + a
