John and rachel share £2400 prize money at a ratio of 2:4. How much do they each get?

Stels [109]

Answer: John:£800

Rachel:£1600

Step-by-step explanation:

Since John and Rachel shared £2400 in the ratio 2:4, it means that £2400 was equal to(2+4) units, which is 6 units.

Thus, each unit is £2400/6= £400

Hence, John got £400x2=£800, and Rachel got £400x4=1600.

Hope u understand my solution. :)
