Question 1

i) Five hundred twenty five and forty hundredths

525+40100 = 525.40

ii) Twelve and thirty five thousandths

12+351000 = 12.035

iii) Fifteen and seventeen thousandths

15+171000 = 15.017

iv) Eighty eight and forty eight hundredths

88+48100 = 88.48

Question 2

i) 137+\(\frac{5}{100}\)

We have 1 hundred, 3 tens , 7 ones and 5 hundredths. Therefore , the decimal is 137.05

ii) 20+9+\(\frac{4}{100}\)

We have 2 tens, 9 ones and 4 hundredths. Therefore , the decimal os 29.04

Question 3

i) \(\frac{8}{100}\)

We have 8 hundredths. Therefore , the decimal is 0.08

ii) \(\frac{300}{1000}\)

In its lowest form , the fraction is 310. We have 3 tenths. Therefore , the decimal is 0.3

iii) \(\frac{18}{1000}\)

We have eighteen thousandths. Therefore the decimal is 0.018

iv) \(\frac{208}{100}\)

208100=200100+8100=2+8100

We have 2 and 8 hundredths. Therefore , the decimal is 2.08

  1. \(\frac{888}{1000}\)

8881000=8001000+801000+81000=810+8100+81000

We have 8 tenths, 8 hundredths and 8 thousandths. Therefore , the decimal is 0.888

Question 4

i) \(12\frac{1}{4}\)

1214=12+14

=12+254(25)=12+25100 =12.25

ii) 718 = 7+18

7+1(1258)(125) = 7+1251000 = 7.125

iii) 5120 = 5+120

5+1(520)(5) = 5+510 = 5.05

Question 5

i) 0.04

= 0+0.04

= 0+4 hundredths

= 0+4100

=125

ii) \(7\frac{1}{8}\)

2.34

= 2+0.34

= 2+34 hundredths

=2+34100

=2(100100) + 34100

= 200100+34100

= 234100

= 11750

iii) \(5\frac{1}{20}\)

0.342

= 0+342 thousandths

= 3421000

= 171500

iv) 1.20

= 1+0.20

= 1+20hundredths

= 1+20100

= 100100+20100

= 120100

= 65

v) 17.38

= 17+0.38

= 17+38 hundredths

= 17+38100

= 17(100100) +38100

= 1700100+38100

= 1738100

= 86950

Question 6

i) Here, we have 2 tens , 9 ones, 4 tenths and 1 hundredths. Therefore , the decimal is 29.41

ii) Here, we have 3 tens, we have3 tens, 4 tenths , 8 hundredths and 3 thousandths. therefore , the decimal is 30.483

iii) Here, we have 1 hundred, 3 tens, 7 ones and 5 hundredths. Therefore , the decimal is 137.05

iv) Here, we have 7 tenths , 6 hundredths and 4 thousandths . therefore , the decimal is 0.764

v) Here, we have 2 tens, 3 ones, 2 tenths and 6 thousandths. Therefore , the decimal is 23.206

vi) Here, we have 7 hundreds, 2 tens, 5 ones and 9 hundredths. therefore , the decimal is 725.09
