if the ratio of milk and water in 45 litre is 7:2. if 4 litre water is added what will be the new ratio.​

5 : 2

Step-by-step explanation:

sum the parts of the ratio, 7 + 2 = 9 parts

Divide the quantity by 9 to find the value of one part of the ratio

45 litres ÷ 9 = 5 litres ← value of 1 part of the ratio , then

7 parts = 7 × 5 = 35 litres

2 parts = 2 × 5 = 10 litres

In 45 litres there is 35 litres of milk and 10 litres of water

Adding 4 litres of water gives

35 : 14 = 5 : 2

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
