Karrem says that the ratio 4:1 is eqivilent to the ratio of 12:9 because 4+8=12 and 1+8 =9 is karreem correct

Mariana [72]

Answer:

No, Kareem is incorrect.

Step-by-step explanation:

Kareem says that the ratio of $\frac{4}{1}=\frac{12}{9}$ because 4 + 8 = 12 and 1 + 8 = 9

But the correct way to rewrite the ratio 4 : 1 is,

$\frac{4}{1}=\frac{4\times 3}{1\times 3}$

Which becomes as,

$\frac{4}{1}=\frac{12}{3}$

Therefore, Kareem is not correct.

Correct ratio equivalent to 4 : 1 is 12 : 3.
