Question

Find the unknown value in the proportion a) 8:3 = 24:x b) 9:2 = x:12

Answer 1

Answer:

$a) \frac{8}{3} = \frac{24}{x} \\ x = \frac{24 \times 3}{8} \\ x = 3 \times 3 = 9$

$b) \: \frac{9}{2} = \frac{x}{12} \\ x = \frac{9 \times 12}{2} \\ x = 9 \times 6 = 54$

Answer 2

Answer:

a.) 8:3 = 24: 9  b.)9:2 = 54: 12

Step-by-step explanation:

a. 8:3 = 24: x

=if, 8 x 3= 24

we multiply 3 by 3 to find x

=3x 3 = 9

so x= 9;

= 8:3 = 24: 9

b.) 9:2 = x:12

if; 2x 6= 12

we multiply 9 by 6 to 54

= 9 x 6=  54

so; x = 54

= 9:2 = 54: 12
