Which of the following option(s) is/are correct for a,b and c represented on the number line below.
(each hops are of equal length)
Open in App
Solution
The correct option is C a=−10
Number of hops =3
Length of each hops =0−(−5)=0+5=5
Given figure represents multiplication of -3 and 5, as we are making 3 hops of 5 to the left(in the negative direction).
a=−5−5=−10
and b=a−5=−10−5=−15
Also, b=Number of hops×Length of each hops
=−3×5
=−15
