Question

Which one of the following represents the number 8:
(a) \[ \require{enclose}\enclose{circle}{|||||}|||\]
(b) \[\require{cancel}\bcancel{|||}\require{cancel}\bcancel{|||}\]
(c) $\require{cancel}\bcancel{|||||}||$
(d) $\require{cancel}\bcancel{||||}|||$

Answer 1

Hint: To draw a tally mark, we will draw the first four lines vertically and each of the fifth line runs diagonally over the previous four vertical lines, i.e. from the top of the first line to the bottom of the fourth line. To draw the tally mark of 8, we have to draw the tally mark of 5 and 3 since 8 is the sum of 5 and 3.

Complete step by step answer:
We have to find the tally mark representation of 8. We know that tally marks are a form of numeral used for counting. We generally write the tally marks as a group or set of five lines. Each line denotes one. The symbol used for this is ‘|’. So to draw a tally mark, we will draw the first four lines vertically and each of the fifth line runs diagonally over the previous four vertical lines, i.e. from the top of the first line to the bottom of the fourth line.
We can write 8 as the sum of 5 and 3
$\Rightarrow 8=5+3$
To represent 8 in tally marks, we have to draw the tally mark for 5 and 3
Tally mark of 8 $=\require{cancel}\bcancel{||||}|||$

So, the correct answer is “Option d”.

Note: Students have a chance of making a mistake by drawing the diagonal line after 5 vertical lines. The diagonal line appears for numbers equal to and greater than 5. We also call tally marks as hash marks. They are a unary numeral system.
