# 240 ÷ (-840). Write the following as rational numbers in their standard forms

**Solution:**

It is given that

240 ÷ (-840)

We can write it as

240 ÷ (-840) = 240/ (-840)

__HCF__ of 240 and 840 is 120

Dividing both __numerator__ and denominator with HCF

(240 ÷ 120)/ (-840 ÷ 120) = 2/-7

Multiplying both numerator and __denominator__ by -1

= [2 × -1]/[-7 × -1]

= -2/7

Therefore, the standard form is -2/7.
