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

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

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

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

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

You lost me at 5:33. How do you get the "2" ?? Thanks
@Mathemagiciann2 ай бұрын
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

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

If we know 80% of a number, how do we find 100%?
@Mathemagiciann2 ай бұрын
100% of a number is itself. If you apply the formula, 100/100 is 1 multipled by number is the number itself

@Mathemagiciann2 ай бұрын
That would be 4000 ÷ 80 ×100
@Mathemagiciann2 ай бұрын
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
