Question

express each of the following rational number in standard form (ii) 24/-42 step by step
​

Answer 1

Answer:

-4/7

Step-by-step explanation:

a rational number is said to be in standard form when the number's numerator and denomination dosen't have any common factors -

therefore to bring this condition we divide the numerator and denominator by H C F of 24 and 42 ( we will put negative sign in numerator at last)

factors of 24 = 1,2,3,4,6,8,12,24

factors of 42 = 1,2,3,6,7,14,21,42

therefore HCF=6

so, 24 /42 = 24/6 = 4/7 putting' - ' sign on numera

42/6

-tor we get -4/7
