How To Find The Percentage of a Number

[@Mathemagiciann]

At 5:33, it is supposed to be multipled by 2/2

[@bridesnyc]

18% of 39 just move 2 steps to the left 0.18x39= 7.02 (why 2 steps to the left? because its 100% 00 _2 zeros

THANKS MATE

[@Mathemagiciann]

Your welcome

[@syedbasit340]

Bro this is soo simple to understand

[@Mathemagiciann]

Glad to hear that

24% of 60, if you know 10% is 6, that 2 times for 20% is $12.00 and 1% is .60 and that times 4 is $2.40 you get $14.40 when added together. You could do it mentally

[@Mathemagiciann]

Yes correct everyone has their way of solving

[@syedbasit340]

Does this method work for any number??

[@syedbasit340]

5:57 I meant this

[@Mathemagiciann]

Yes

[@bridesnyc]

Simple math 18% of 39 move 2 spaces to the left on the 18% 0.18x39=7.02 or multiply 18x39=702 and move 2 spaces to the left on the result = 7.02

[@Mathemagiciann]

Exactly

[@syedbasit340]

@@Mathemagiciann ohh I see

[@bridesnyc]

40% of 700...easy pieze (1) move 2 steps to the left on the 40% 0.40 x700= 280

[@Mathemagiciann]

Yeah everyone has their way of doing this. Like just multiply 4 by 7 which is 28 and move the decimals accordingly

[@Salamander0111]

You lost me at 5:33. How do you get the "2" ?? Thanks

[@Mathemagiciann]

What I meant was let's there is 1/1, is it the same as 2/2 or 100/100? It is right? The same way, 351/50 is the same as 702/100. The reason we wanted a 100 in the denominator was so that we can just easily move the decimal point 2 places to the left

[@Mathemagiciann]

Also it is technically not multipled by 2 but actually by 2/2. Just a property of fractions

[@Mathemagiciann]

I made a mistake there sorry

@@Mathemagiciann no worries . Brushing up on my mathematics myself ☺️

Let me know if anything else is not clear

If we know 80% of a number, how do we find 100%?

[@Mathemagiciann]

100% of a number is itself. If you apply the formula, 100/100 is 1 multipled by number is the number itself

[@trailerpark948]

@@Mathemagiciann I mean if 4000 is 80%, how do we find 100%?

[@Mathemagiciann]

Ohhh I see

[@Mathemagiciann]

That would be 4000 ÷ 80 ×100

[@Mathemagiciann]

The concept is we are told that 80% is 4000 so to find 1% of our number is 4000 divided by 80. Then to find 100% we will multiply the 1%(50) by 100
