The number is 94 because 94 minus 40 = 54
When 180 is decreased by 40% the result is 108.
When 40 is decreased by 30% the result is 28.
40
It can be.
Let that number be x. So we have, x - 0.3x = 28 0.7x = 28 7x = 280 x = 40 Check.
It is: 75 minus 40 = 35
x-40=36 , x=36+40 , x=76
Multiply 105 by .6 (60%) because if one subtracts 40% of something he/she is left with 60% of the number. 105 (.6)= 63
40% is 30, so decreasing by that amount would leave 45.
60 decreased by 40 is 20.
100% of any number is that number itself. So 100% of 40 is 40
40 x 40 = 1,600
