Question

If there are 8 equal divisions between 7 and 8 on the number line, find the number represented by the fifth division.

• A. 7.125
• B. 7.8
• C. 7.625
• D. 7.5

Answer 1

The correct option is C 7.625

Number of divisions = 8
Value of each division $=\frac{1}{8}$$=\frac{1\times 125}{8\times 125}=\frac{125}{1000}=0.125$
Value of 5 divisions = 0.125$\times$5 = 0.625

Number represented by the fifth such division between 7 and 8 = 7.625
