3. Write each of the following decimals in expanded form:

(i) 67.83

(ii) 283.61

(iii) 24.675

(iv) 0.294

(v) 8.006

(vi) 4615.72

Solutions

(i) 67.83

= 6 tens + 7 ones + 8 tenths + 3 hundredths

= (6 × 10) + (7 × 1) + (8 × 1 / 10) + (3 × 1 / 100)

= 60 + 7 + 8 / 10 + 3 / 100

∴ 67.83 = 60 + 7 + 8 / 10 + 3 / 100

(ii) 283.61

= 2 hundreds +8 tens + 3 ones + 6 tenths + 1 hundredths

= (2 × 100) + (8 × 10) + (3 × 1) + (6 × 1 / 10) + (1 × 1 / 100)

= 200 + 80 + 3 + 6 / 10 + 1 / 100

∴ 283.61 = 200 + 80 + 3 + 6 / 10 + 1 / 100

(iii) 24.675

= 2 tens + 4 ones + 6 tenths + 7 hundredths + 5 thousandths

= (2 × 10) + (4 × 1) + (6 × 1 / 10) + (7 × 1 / 100) + (5 × 1 / 1000)

= 20 + 4 + 6 / 10 + 7 / 100 + 5 / 1000

∴ 24.675 = 20 + 4 + 6 / 10 + 7 / 100 + 5 / 1000

(iv) 0.294

= 2 tenths + 9 hundredths + 4 thousandths

= (2 × 1 / 10) + (9 × 1 / 100) + (4 × 1 / 1000)

= 2 / 10 + 9 / 100 + 4 / 1000

∴0.294 = 2 / 10 + 9 / 100 + 4 / 1000

(v) 8.006

= 8 ones + 0 tenths + 0 hundredths + 6 thousandths

= (8 × 1) + (0 × 1 /1 0) + (0 × 1 / 100) + (6 × 1 / 1000)

= 8 + 0 / 10 + 0 / 100 + 6 / 1000

= 8 + 6 / 1000

∴8.006 = 8 + 6 / 1000

(vi) 4615.72

= 4 thousands + 6 hundreds + 1 tens + 5 ones + 7 tenths + 2 hundredths

= (4 × 1000) + (6 × 100) + (1 × 10) + (5 × 1) + (7 × 1 / 10) + (2 × 1 / 100)

= 4000 + 600 + 10 + 5 + 7 / 10 + 2 / 100

∴ 4615.72 = 4000 + 600 + 10 + 5 + 7 / 10 + 2 / 100

4. Write each of the following in decimal form:

(i) 40 + 6 + 7 / 10 + 9 / 100

(ii) 500 + 70 + 8 + 3 / 10 + 1 / 100 + 6 / 1000

(iii) 700 + 30 + 1 + 8 / 10 + 4 / 100

(iv) 600 + 5 + 7 / 100 + 9 / 1000

(v) 800 + 5 + 8 / 10 + 6 / 1000

(vi) 30 + 9 + 4 / 100 + 8 / 1000

Solutions

(i) The decimal form of 40 + 6 + 7 / 10 + 9 / 100 = 40 + 6 + 0.7 + 0.09

= 46 + 0.7 + 0.09

= 46.79

(ii) The decimal form of 500 + 70 + 8 + 3 / 10 + 1 / 100 + 6 / 1000

= 500 + 70 + 8 + 0.3 + 0.01 + 0.006

= 578.316

(iii) The decimal form of 700 + 30 + 1 + 8 / 10 + 4 / 100 = 700 + 30 + 1 + 0.8 + 0.04

= 731.84

(iv) The decimal form of 600 + 5 + 7 / 100 + 9 / 1000 = 605 + 0.07 + 0.009

= 605.079

(v) The decimal form of 800 + 5 + 8 / 10 + 6 / 1000 = 805 + 0.8 + 0.006

= 805.806

(vi) The decimal form 30 + 9 + 4 / 100 + 8 / 1000 = 39 + 0.04 + 0.008

= 39.048
