Answer:

3/13

Step-by-step explanation:

ratio is another way to say fraction, so we have 21/91.  This can be reduced if we divide by 7: 21/7 = 3, 91/7 = 13.  Now we have 3/13.  You can write it as 3:13 or 3/13.

# [4-5{1-(4-3+1)}] of 100% equals <br><br> a) 50%<br> b)-1%<br> c)zero<br> d)100%
Nikitich [7]

<u>Answer:</u>

To solve this, we need to first evaluate the given expression. We can do that by simplifying the contents of each bracket, starting with the innermost one:

[4-5{1-(4-3+1)}]

⇒ [4 - 5{1 - (2)}]

⇒ [4 - 5{-1}]

⇒ 4 - (-5)

⇒ 4 + 5

⇒ 9

Now we can calculate what 9 out of 100 is:

9 of 100  =  \frac{9}{100}

              ⇒  9%

0.72 in scientific notation
boyakko [2]
Remember that scientific notation always contains a number between 0 and 10 that is multiplied by ten to some power. In this case, to get a number between 0 and 10 (7.2) we would move the decimal point once to the right. Since it is moving to ththe right, the exponent over the 10 will be negative, and it will be -1 because we moved the point once. So the answer is 7.2*10^-1

Hope this helps
