Answer:

No

Step-by-step explanation:

Deshawn is incorrect because a ratio is the proportion of numbers, or the relationship, basically as a fraction. 3/5 does not equal 5/7 because if we use cross multiplying in the equation 3/5=5/7, we multiply the terms by their diagonals. Thus, 3 times 7 does not equal 5 times 5; 21 does not equal 25.
