3000 / 10 = 300 (10%)300 x 9 = 2700 (90%)
90/300 = 9/30 = 3/10 = 3 ÷ 10 = 0.3
3/10 of 300 = 90
assuming question means percent 300 = 100% 30 = 10% 90 = 30% though 30 x 300 = 9,000
Let P be the required percentage. Then :- P/100 = 90/300 P = 100 x 90/300 = 30% 90 is 30% of 300.
300 x 30% = 90 ( 30% of 300 = 90)
3000 / 10 = 300 (10%)300 x 9 = 2700 (90%)
90/300 = 9/30 = 3/10 = 3 ÷ 10 = 0.3
3/10 of 300 = 90
3 tenths of 300-----> 3 tenths = 3/10 or .30-----> of = x (multiply)= 3/10 of 300= 3/10 x 300= .30 x 300= 90
90
3/10 x 90 = 27
Answer 300 ---- Here is why: This is the same as asking .3x=90 so the number is 90/.3 =300 Note, 90/.3 is 90 divided by 3/10 which is 90x10=900 divided by 3.
392 C=100, so CCC is 300 X=10, so XC is 90 (100-10=90) I=1, so II=2 300+90+2=392
$90= 30%/100% * $300= 0.3 * $300= $90
10, 20, 30, 40, 50, 60, 70, 80, 90 and just keep adding 10 until you get to 300.
assuming question means percent 300 = 100% 30 = 10% 90 = 30% though 30 x 300 = 9,000
