Answers
Given : 1.75
To Find : a pictorial representation
Solution:
Numbers with a negative sign are less than zero
Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.
+ sign numbers can be denoted as simply numbers
On a number line the number increases as we move to the right and decreases as we move to the left.
1 : Draw a line and mark some points at equal distance on it as shown in the figure below Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3 and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on
Divide 1 & 2 in 10 equal parts
Then Divide between 7 & 8 th on right from 1 in 10 Equal parts
Then between 1.7 and 1.8
5 right from 1.7 will show 1.75
or 1.75 = 1 + 3/4
Use a Circles divided in 4 parts
one circle complete + other with 3 out of 4 parts shaded as attached
