Answer 1

Answer:

Total cereal mixture is 5·7 kg

Step-by-step explanation:

A cereal mixture contains in rice , wheat and corn

In a ratio of rice, wheat and corn is  $3:7:9$

let the number be x

Rice  $=$  3x

Wheat  $=$  7x

Corn $=$  9x

Total cereal mixture is 19x

Wheat $=$ 2·1 kg

So, Wheat 7x equals to 2·1 kg

7x $=$ 2·1 kg

x $= \frac{2.1}{7}$ kg

x $=$ 0·3 kg

Total cereal mixture is 19x

19 ₓ 0·3 $=$  5·7 kg
