Answer 1

The ratio is 7:4

Step-by-step explanation:

1. Let's first simplify the question by converting decimal into fractions
2. Numerator 2.1 is nothing but 21 ÷ 10
3. Denominator 1.2 is nothing but 12 ÷ 10
4. Now just express this division (21÷10/12÷10) in terms of multiplication by multiplying 21÷10 with the reciprocal of 12 ÷ 10
5. So it becomes 21÷10 × 10÷12
6. Strike out both the 10 and we get 21÷12
7. On simplifying 21÷12 we get 7/4
