400 ml squash is made by mixing 50 ml of cordial with water. what fraction of the drink is water?give your answer in its simples
Tasya [4]

squash = cordial + water

400 ml = 50 ml + x ml

350 ml = x ml

Therefore, 350 ml are water.

350 ml / 400 ml = 0.875 = \frac{350}{400} = \frac{35}{40} = \frac{7}{8}

So the answer is 7 / 8
