(6) c. 3000000 + 300000 + 30000 + 200 + 30 + 6 (7) d. ten According to the question, we have to f ind the number or place which is 100000 times smaller than 1000000. We shall get the answer by dividing 1000000 by 100000 keeping in mind that the term division means repeated subtraction. 1000000 100000 = 10 which can be expressed as ten in words. Step 4 Hence, the answer is ten. (8) d. 51118701
(9) 9999998 ID : gb-5-large-numbers [4] For a number to be as large as possible, all of its digits should be as large as possible. Theref ore largest 7 digit number should be 9999999. The number just bef ore the largest 7-digit number will be one less than it, that is: 9999999-1 = 9999998 Thus, the number just bef ore the largest 7-digit number is 9999998. (10) (11) (12) 10000000 897280 1136889 (13) A) B) 166286 472891
(14) 8 ID : gb-5-large-numbers [5] Let us f irst count the number of digits in the whole number 90000000. Counting starting f rom 9 being the f irst digit f ollowed by 7 zeroes shows that there are 8 digits. Hence, there could be 90000000 8-digit whole numbers in number system. Bef ore we can conclusively say so, we will need to verif y it. Step 4 In order to prove that there are 90000000 8-digit whole numbers in the number system, let us subtract the largest 8-digit number with the smallest 8-digit number and add the dif f erence with 1: (99999999-10000000) + 1 = 89999999 + 1 = 90000000 Step 5 We should now conclude that there are 90000000 8-digit whole numbers in the number system. (15) 10 When a digit moves one place to the lef t, it s place value becomes 10 times greater. A number becoming ten times greater can be seen as getting multiplied by a f actor of 10. Thus, the place value of the digit that moves one place to the lef t changes by a f actor of 10.
