Each person at a picnic chose atleast one piece of a fruit one third of the people chose an apple three -quaters of the people chose a orange what fraction of the people chose both of them

-1/12x

Step-by-step explanation:

Let total people at the picnic=x

People who chose apple= 1/3x

People who chose orange= 3/4x

People who chose each of the fruit= People who chose apple + People who chose orange

=1/3x + 3/4x

= 4x+9x / 12

=13/12x

People who chose each of the fruit= 13/12x

what fraction of the people chose both of them?

Fraction of the people who chose both fruits= Total people at the picnic - People who chose each of the fruit

=x - 13/12x

=12x- 13x /12

= -1/12 x
