*ahem* the actual Awnser is 79.25 because 63.4 divided by 72 is 0.8805 and if you multiply that by 90 you get 79.25
The Answer would be 2.8 because when you subtract -16 - 8 you get -24... then you divide that by 2 and you should have -12 + 25 / 5 + 1.... from there you can move the one from the end and add it to 25 and you get -12 + 26 / 5.... and all you have to do is simple math there... -12 + 26 = 14... and 14 / 5 == 2.8
ANSWER == 2.8

Answer:
Fraction of drink that is water = = 0.875 = 87.5 %
Explanation:
400 ml of squash is made by mixing 50 ml of cordial with water.
Total volume of squash = 400 ml
Total volume of cordial = 50 ml
Total volume of water = 400 - 50 = 350 ml
Fraction of drink that is water = Volume of water/ Volume of squash
= 350/400
= 7/8
= 0.875 = 87.5 %
