How to find a percentage of a number

Example:        30% off of 120 dollars

Answers

Answer 1
Answer: Times a number by a percent. First turn 30% Ino .3 by putting the decimal point 2 times to the l .
Answer 2
Answer: each percent is basically a decimal in a different form. So 30% .3 (just move the decimal 2 times). Now multiply 120 by .3 and get 36. Just subtract 36 from 120 and get 84.

Explanation:

Treat it as a normal equation - except that you have to add fractions as coefficients rather than integers.Improper fractions will probably be best for adding because later you can cross multiply.

0.4, 60%, 1/5

Answers

1/5, 0.4, then 60%.  Because if you multiply 0.4 by 100, you get 40%, and then you do the same thing for 1/5.


1/5 , 0.4, 60%        1/5 converts by dividing 5 into the 1 =0.2 or 20%   the 0.4 = 40% move the decimal point to the right to convert from decimal to the percentage then line

up from smallest number to largest   1/5, 0.4,  60%

10 less than the quotient of g and 3

Answers

Answer:

Given that: 10 less than the quotient of g and 3.

"The quotient of" is a, / (division) operation.

" the quotient of g and 3" is translated to  (g)/(3)

so, " a Less than b " translated to b - a

Then;

"10 less than the quotient of g and 3" means (g)/(3) -10

Therefore, the algebraic expression of 10 less than the quotient of g and 3 is,  (g)/(3) -10
(g/3)-10
That is the mathematical expression.
Hope this helps.

Find the next three term in the sequence-8, 24,-72,216

Answers

Answer:

- 648, 1944, - 5832

Step-by-step explanation:

the terms form a geometric sequence with

common ratio r = (-72)/(24) = (24)/(-8) = - 3

to obtain the next term in the sequence multiply the previous term by r

216 × - 3 = - 648

- 648 × - 3 = 1944

1944 × - 3 = - 5832

the next 3 terms are - 648, 1944, - 5832
