Question

The tailor works 8.5 hours every day. How many hours does he work in 6.5 days?

• A. 54.50
• B. 54.25
• C. 55.25
• D. 55.50

Answer 1

The correct option is C 55.25

Total number of hours worked by the tailor in a week = 8.5 x 6.5 hours
= 85/10 x 65/10
We have learned to multiply two fractions, so we will multiply these two.
$\frac{85}{10}\times \frac{65}{10}$$=\frac{5525}{100}$
if you divide a decimal number by 10, 100, 1000… then the decimal point shifts to the left by as many zeros as in 10, 100, 1000….
5525/100 = 55.25 hours
