Remember the rule, if the number is a decimal, it should be multiplied by 10^-n.
Formula = a * 10^-n
0.0008235 in scientific notation
=> 8.235 * 10^-n
There are 3 0s from the left side of the numbers and going to the decimal point.
<span>So, we're</span> gonna move 3 to the left
=> 8.235 * 10^-3.
Negative because it is a decimal number.
So $1600 is how much it will go done!
And $6400 is how many it will be after 20% off
because 8000*0.20=1600
(I hope I'm right)
Answer:
(1) 1/8
(2) 1/12
(3) 1/16
(4) 1/20
Step-by-step explanation:
We need to find multiple divisions, it says 1/4 divided by 2 then go back to 1/4 and divide it again but by 3 then go back to it again and divide it by 4 then go back to 1/4 and divide it by 5.
We will take one by one
(1) 1/4 divides by 2 will be = 1/8
(2) 1/4 divided by 3 = 1/12
(3) 1/4 divided by 4 = 1/16
(4) 1/4 divided by 5 =1/20
These results are obtained by dividing the given parts, as the given Numerator is in fraction so whatever will be divided from the fractional numerator will get multiplied with the denominator.
Answer:
Step-by-step explanation:
Y+6=2x-6
6+6=2x-y
12=2x-y
Regrouping is only done into lower place values. For example, tens to ones and hundreds to tens.
