2 with 10 remaining 100 - 10 = 90 = 45 x 2
1,000 if u add 55 and 45 u get 100 and the differance of 55 and 45 is 10 so multiply 100 and 10 to get 1,000
The triangular numbers between 1 and 100 are: 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91.
10/100 * 45 = 4.5
3 1/10 or 31/10
% rate = 10/45 * 100% = 22.22%
Converting percentage to a decimal: 4.5% = 4.5 / 100 = 0.0454.5% of 100= 4.5% * 100= 0.045 * 100= 4.5
2 with 10 remaining 100 - 10 = 90 = 45 x 2
45x10 (pay attention to what 45,and 10 eqaual)
45/100 - 20/100 = 25/100 = 1/4
-10
45 + 55 = 100 45 = ½(9 x 10) 55 = ½(10 x 11)
1,000 if u add 55 and 45 u get 100 and the differance of 55 and 45 is 10 so multiply 100 and 10 to get 1,000
Percent means hundredths. So 10% of something = 10/100 = 1/10 of it. 10% of $45.00 = (10/100)(45.00) = $4.50 So 10% off $45 is $4.50 off $45 45.00 - 4.50 = $40.50
0.8 is 8/10 or 80/100. 0.45 is 45/100. 80/100 is greater than 45/100.
Expressed as a percentage, 10/45 x 100 = 22.2 recurring (that is, 22.2222...) percent.
The triangular numbers between 1 and 100 are: 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91.
