Question 1.

Where else can we see such ‘non-decimals’ with a decimal-like notation? Class 7

Solution:

For example, this section has been marked as 3.8.

Question 2.

Convert the following fractions into decimals: Class 7

(a) [latex]\frac {5}{100}[/latex]

(b) [latex]\frac {16}{1000}[/latex]

(c) [latex]\frac {12}{10}[/latex]

(d) [latex]\frac {254}{1000}[/latex]

Solution:

(a) [latex]\frac {5}{100}[/latex] = 0.05

(b) [latex]\frac {16}{1000}[/latex] = 0.016

(c) [latex]\frac {12}{10}[/latex] = 1.2

(d) [latex]\frac {254}{1000}[/latex] = 0.254

Question 3.

Convert the following decimals into a sum of tenths, hundredths and thousandths: Class 7

Solution:

(a) 0.34

(b) 1.02

(c) 0.8

(d) 0.362

Solution:

(a) 0.34 = [latex]\frac {3}{10}[/latex] + [latex]\frac {4}{100}[/latex]

(b) 1.02 = 1 + [latex]\frac {2}{100}[/latex]

(c) 0.8 = [latex]\frac {8}{10}[/latex]

(d) 0.362 = [latex]\frac {3}{10}[/latex] + [latex]\frac {6}{100}[/latex] + [latex]\frac {2}{1000}[/latex]
