Question 4 - Page 73 In each case below use the digits 4, 1, 8, 2, and 5 exactly once and try to make a decimal number as close as possible to 25.Lets do one by one For Now, Digits before decimal point are 25 Digits left are 4, 1, 8 – and we need to make the smallest number. So, 148 Thus, number closest to 25 is Another number could be 24.851 For Now, This has 1 digit before decimal point So, we need largest decimal number with 1 digit before decimal point We have digits 4, 1, 8, 2, 5 So, largest number could be 8.542 Thus, number closest to 25 is For Now, This has 3 digits before decimal point So, we need smalles decimal number with 3 digit before decimal point We have digits 4, 1, 8, 2, 5 So, smallest number could be 124.58 Thus, number closest to 25 is
