90% of 80%

1.) (90/100) X (80/100) = (7200/10000)
2.) 7200/10000 = N/100
3.) solving we get , N=72

0.9x0.8=0.72 Therefore your answer is 72.

(90/100) (80/100)=n/100----------------9 8=72

90X.8=72 or 80X.9=72

Since we want 90% of 80%, we assume the whole quantity to be 100 and then we find out its 80% which is 80. Now, the 90% of 80 is 72. And bingo. :)

90*80=7200 and 7200/10000=.72 that is 72%

90% x 80% = N% Logo: 0,90 x 0,80 = 0,72 , equivalente a 72%

90%=0.9,
80%=0.8,
(0.8)x(0.9)=0.72=72%

% means per 100. 90%x80% means 90/100x80/100. This equals 72/100 which is 72%. Therefore N=72.

(90/100) (80/100)=N/100 18/25=N/100 N=18/25 100=72

90/100 x 80/100 = 7200 / 10000 = 72/100 = 72%. N = 72. Answer : 72

90% = 90/100, 80% = 80/100, so 90% x 80% = (90/100) x (80/100) = 0.9 x 0.8 = 0.72 0.72 = 72/100 = 72%

Problem: 90% * 80% = N%

My solution: 90 / 10 = 9

9 * 8 = 72

N = 72

Although it could also have been solved similarly: 80 / 10 = 8; 8 * 9 = 72. Works either way.

Not sure if this way makes a whole lot of sense but it's how I did it. Like if this made sense to you.

90*80=7200 100^2=10000 Then, 7200/10000 = 72/100 72% <------- :))

90% x 80% = .90 x .80 = .72 =72% so N=72

90% = 9/10 MULTIPLY 80% = 8/10 which equals 9 x 8 = 72 and you cross out all the percent signs in the questions which leaves you with 72 as your answer.

7200/10000=72%

Write a solution. 90*80=7200 but it is in percentage form so, 7200/100=72..:)

90(80) = 7200 Then divide by 100.

90*80/100=72%

7200/100 * 100 = 72 %

90%=90/100

80%=80/100

N%=(90/100)*(80/100)=72

90% x 80% = N%

---> 90/100 x 80/100 = 7200/10000

7200/10000 be simplified is 72/100

72/100 = 72%

N=72

.9*72

90/100 = .9 80/100= .8 .9 * .8 = 7.2 7.2/100 * 10 = 72

9*8=72

90/100*80/100=7200/10000=72/100=72%

90%*80%=N% , 90/100 * 80/100 , 9x8/100 , =72/100=72%

90%= .9 AND 80%=.8 THEN I MULTIPLY .9 X .8 = 0.72 SO THE FINAL ANSWER IS 72%

8= 10% of 80, so 80-8=72=90% of 80.

90% of 80% is 72....because for example 80%=100,so 10%=8....same way he is asking 90%of 80%..so 8+8+8+8+8+8+8+8+8=72

(90 x 80)/100=N
OR (90/100) x (80/100)= (N/100)

0.9 x 0.8 = 0.72 = * 72% *

90% = 0.9 80% = 0.8 90% x 80% = (0.9 x 0.8)100 = (0.72)100 = 72%

90% of 80% = ? 80/100=0.8 0.8*90=72 therefore, the 90% of 80% is 72.

its 90/100 x80/100 thats= 72/100

90/100 multiplied by 80/100 = 0.72

0.72 x 100 = 72%

72%

90% * 80% = 90/100 * 80/100 =720/1000=72% therefore N=72

90% = 90/100 and 80%=80/100 90/100*80/100= 7200/100 Simplest form=720/1= 720

90% = .9 80% = .8 .8 .9 = .01 * (8 9) Since we are doing percents, .01 is useless so 8*9 = 72 Thus, $\boxed{72}$ percent

Those were in percentages., so divide the 90, 80 by hundred and then multiply them both. You will get a value which when multiplied by 100 gives the value of N in percentage

>100* (90/100)= 90 >90*(80/100)=72

multiply 90/100 by 80/100 the answer comes 7200/10000 then cut the two zeros of 7200 by two zeros of 10000 then the answer comes 72/100 which will be equal to 72% so this is the answer

90% is equal to .9

80% is equal to.8

multiply them and you get .72

.72 is = to 72%

90/100x80/100=72/100=72%

90/100 * 80/100=7200/10000=72/100=72%

80/100= 0.8, then 0.8 times 90= 72%

.9 .8=.72 100=72

90/100×80/100×100=72

90%* 80%=.72 = 72%

=90% x 80% =90/100 x 80/100 =7200/10000 =72/100 =72x 1/100 =72%

90% 80%=N% (90/100) (80/100)=N/100 (90*80)/100=72

90 multiply by 80 then divide by 100

90% x 80% =720% 720/10= 72

I multiplied .90 x .80 n I got 72

90% x 80% = 72% because you have to change the 90% and 80% into a decimal. Then you multiply them as there decimals, 0.9 x 0.8= 0.72. Now to change that into a percent we have to multiply it by 100. When i multiply 100 x 0.72 I get 72. ( Also known as 72%) And that is how i came up with the answer 72%!

You make 90 into .90 and 80 into .80 and multiply. .90x.80=0.72 , move the decimal two places back.

you have to multiply 90% and 80% then just type in 72.

I multiplied .90 times .80 and I got 72

90/100 x 80/100 = 9/10 x 8/10 = 72/100

copy in google

Well I thought of it this way: What is 80 % of 90 the number?

subtracting 20 % of what 90 is would give you that number

10 % is 9 therefore 20 % is 18

90-18= 72

Maybe a bit convoluted but that's how I got there
