Answer:

No.

Step-by-step explanation:

Ratio of any objects can be calculated by dividing the two objects with the common number.

Boys in the sixth grade = 35.

Girls in the sixth grade = 42.

Ratio of boys to girl = $\frac{boys}{girls}$

Ratio = $\frac{35}{42}$

Ratio = 5:6. (the numbers are divided by 7).

Thus, the ratio is 5:6 and not the 5:7.

Thus, Lonnie is not correct.
