4 Answers ID : in-4-decimals [4] (1) Let s f irst convert the number name into number/f raction. So, one Ten thousandths can be written as: By converting the f raction into decimals, we get: = Theref ore, the number one Ten thousandths in decimal f orm is (2) Decimals with the same number of decimal places are called Like Decimals. T he numbers given here are theref ore Like Decimals. We need to subtract f rom Theref ore, must be placed on top and below. The digits of the two numbers must be placed according to their place values. Let us now do the subtraction of the two numbers digit by digit, starting f rom the hundredths and borrowing if needed: Thousands Hundreds Tens Ones. Tenth Hundredth Step 4 Hence, when we subtract f rom 566.5, we get
5 (3) ID : in-4-decimals [5] is a mixed f raction. A mixed f raction is a combination of a whole number and a 0 proper f raction. In the mixed f raction , 44 is a whole number and 73 0 is a proper f raction. To convert the mixed f raction into decimal, we shall f irst convert the proper f raction into a decimal number and add it to the whole number Step 4 The proper f raction 73 0 can be written as a decimal number as Adding the whole number 44 to the decimal number 0.73, we get Step 5 Theref ore, the answer is (4) 8 Tenths Let s use the place value chart and f ind where 8 is placed: Lakhs T housands Ones T enths Hundredths T housandths T en thousandths T L L T T H T H H T O. (1/) (1/0) (1/00) (1/000) Legend: TL - Ten Lakhs, L - Lakhs, TTH - Ten Thousands, TH - Thousands, H - Hundreds, T - Tens, O - Ones. From the above table, we observe that 8 is placed under the Tenths place. Hence, the place value of 8 in is 8 Tenths. (5) A) 11.5 B) 0.6 C) 0.2
6 D) 0.9 ID : in-4-decimals [6] (6) a Let us f irst convert the number names into numerals: 9 Ten thousandths = = Tenths = 69 = Ten Thousands = = Let s f irst add the decimal numbers as below: Lakhs T housands Ones T enths Hundredths T housandths T en thousandths T L L T T H T H H T O. (1/) (1/0) (1/00) (1/000) T otal Legend: TL - Ten Lakhs, L - Lakhs, TTH - Ten Thousands, TH - Thousands, H - Hundreds, T - Tens, O - Ones. Let us now add the decimal numbers with the whole number: Lakhs T housands Ones T enths Hundredths T housandths T en thousandths T L L T T H T H H T O. (1/) (1/0) (1/00) (1/000) T otal Step 4 Theref ore, by adding 9 Ten thousandths and 69 Tenths together to 72 Ten Thousands, we get
7 (7) a. 4 Tenths ID : in-4-decimals [7] Let s use the place value chart and f ind where 4 is placed: Lakhs T housands Ones T enths Hundredths T housandths T en thousandths T L L T T H T H H T O. (1/) (1/0) (1/00) (1/000) Legend: TL - Ten Lakhs, L - Lakhs, TTH - Ten Thousands, TH - Thousands, H - Hundreds, T - Tens, O - Ones. From the above table, we observe that 4 is placed under the Tenths place. Hence, the place value of 4 in is 4 Tenths. (8) c (9) A) b Given, = Let us assume the missing number be x. Theref ore, x = or = x or x = Now, we have to subtract f rom Theref ore, x = Thus, = 68.38
8 B) c ID : in-4-decimals [8] Given, = Let us assume the missing number be x. Theref ore, x = or = x or x = Now, we have to subtract f rom Theref ore, x = Thus, = C) c Given, = Let us assume the missing number be x. Theref ore, x = or = x or x = Now, we have to subtract f rom Theref ore, x = Thus, = 11.59
9 D) b ID : in-4-decimals [9] Given, = Let us assume the missing number be x. Theref ore, x = or x = Now, we have to subtract 51.2 f rom Theref ore, x = Thus, = () c Let s f irst convert the number name into number/f raction. So, eight Tenths can be written as: 8 By converting the f raction into decimals, we get: 8 = 0.8 Theref ore, the number eight Tenths in decimal f orm is 0.8. (11) c. 9 8
10 (12) A) ID : in-4-decimals [] First, let us identif y all the whole numbers and add them as below: = 188 Let us now convert the f raction numbers into decimals: = 0.1 = = Let s use the place value chart to add the whole numbers and the decimal numbers as: Ones T enths Hundredths T housandths H T O. (1/) (1/0) (1/00) T otal Legend: H - Hundreds, T - Tens, O - Ones. Step 4 Hence, the answer is
11 B) ID : in-4-decimals [11] First, let us identif y all the whole numbers and add them as below: = 519 Let us now convert the f raction numbers into decimals: = 0.8 = = Let s use the place value chart to add the whole numbers and the decimal numbers as: Ones T enths Hundredths T housandths H T O. (1/) (1/0) (1/00) T otal Legend: H - Hundreds, T - Tens, O - Ones. Step 4 Hence, the answer is
12 (13) 0.68 ID : in-4-decimals [12] If we look at the f igure, we notice that, there are total 0 boxes. 30 of 0 represents 0.3. Theref ore, 1 of 0 represents = 1 = The dif f erence of the boxes in the given f igures = = 68 and hence 68 of 0 represents = 68 = Thus, the result of is (14) 2.43 (15) True
