Answer:

m(missing number)= 10.8 or rounded is 11

Step-by-step explanation:

For the equation

9 x 20= m x 24

The cross product is

9×24=20×m

Solving for m

m=9×24/20

and reducing

m=10.8

Solution by Proportion

Since the equation is an equality

If

24 ÷ 20 = 1.2

Then it is true that

m ÷ 9 = 1.2

Solving for m

m = 9 × 1.2

m = 10.8

Rounded

11`because its closer to 11 then subtracting the decimal!

hope this helps!! tell me if i have anything wrong:)
