The remainder obtained when 4⁹⁶ is divided by 6 is

• 3

• 4

• 5

• 6

$3\frac{5}{6} + 6\frac{1}{7} - 2\frac{1}{3} -1\frac{1}{2} = ?$

• $6\frac{1}{7}$

• $6\frac{1}{21}$

• $6\frac{5}{28}$

• $6\frac{1}{14}$

$5 + \frac{1}{5 + {\displaystyle \frac{1}{5 + {\displaystyle \frac{1}{5 + ...}}}}}$

• $\frac{11}{2}$

• $\frac{\sqrt{29} +\hspace{0.17em}1}{2}$

• $\frac{\sqrt{13} + 1}{2}$

• $\frac{\sqrt{29} + 5}{2}$

What will come in place of question mark (?)

$\frac{17.28 ÷ ?}{3.6 \times 0.2} = 2$

$\mathrm{A} \mathrm{student} \mathrm{writes} \frac{10 \mathrm{cm}}{12 \mathrm{cm}} = \frac{5}{6}\mathrm{cm}$

$\frac{15 \mathrm{cm}}{15 \mathrm{m}} = 1000\mathrm{m}. \mathrm{This} \mathrm{student}$

• can reduce fractions to lowest term correctly and can write the units properly

• has concept of units, conversion of units, fractions but missed the concept that ratio does not have units

• always commits clerical error of writing unit with ratio

• has clear concept of units and their conversion
