Question

To make mango smoothie, Fritzi mixed some mango and water in the

ratio of 3:4. She made 2800 ml of such smoothie. How many milliliters of water
did she use? A. 1600 B. 1500 C. 1400 D. 1300

Answer 1

Think like this. If you add 3 parts of mango you have to add 4 parts of water according to the ratio. So whole mixture contains 3 + 4 = 7 parts.

Consider the ratios as fractions,

Mango - 3/7
Water - 4/7

Let’s see how many milliliters of water in 2800ml.

If you make a 7ml solution water contains 4ml. Then,

For 2800ml ?

2800 x (4/7)
=1600

Answer is A-1600
