Answer:

Step-by-step explanation:

Express the following rational number in its standard form: -15/35

Solution:

Given, the rational number is -15/35

We have to express the given rational number in its standard form

We know that, to reduce the rational number to its standard form, we divide its numerator and denominator by their HCF

15 = 3 × 5

35 = 5 × 7

HCF of 15 and 35 = 5

Now, 15/5 = 3

-35/5 = -7

So, -15/35 = 3/-7

Therefore, the standard form of -15/35 = 3/-7
