For 100 people, we will need 100/25=4 times the listed quantities.
Saussage rolls = 50*4 = 200 saussage rolls
Sandwiches = 75*4 = 300 sandwiches
Samosas = 25*4 = 100 samosas
50 have been eaten and 150 have not been eaten.
The absolute value is the value of the number without the sign. So in this case it's 3 and -3
Convert 3/4 to a denominator of 8 by multiplying by two, getting you:
6/8 + 1/8
Add those and you get D) 7/8
