$\huge\mathfrak\blue{ Good Evening}$ $\huge\mathfrak\red{ }$ $\huge\mathfrak\green{ }$

$\mathfrak\pink{ Here \: your \: answer \: mate}$ $\huge\mathfrak\red{ }$ $\huge\mathfrak\green{ }$

in order to calculate the longest tape we need to calculate the HCF of 13.6 metre ,12.4 m and 5.6 m .

so, 136/10 = 1/10 *(2*2*2 *17 ) .......(1)

124/10= 1/10*( 2 *2*31)......( 2)

56/ 10 = 1/10 *(2*2*2*7)......(3)

taking out common factors from( 1 ), (2) & (3) we get

HCF = 2*2/1) = 0.4

Answer 2

Step-by-step explanation:

in order to calculate the longest tape we need to calculate the HCF of 13.6 metre ,12.4 m and 5.6 m .

so, 136/10 = 1/10 *(2*2*2 *17 ) .......(1)

124/10= 1/10*( 2 *2*31)......( 2)

56/ 10 = 1/10 *(2*2*2*7)......(3)

taking out common factors from( 1 ), (2) & (3) we get

HCF = 2*2/1) = 0.4
