Please help is how you do it?

Problems 5, 7A, and 7C are the only ones with correct answers.

But for 1 - 6, you're also supposed to color in the same amount of the big square,
and for 7, you're also supposed to mark a dot on the number line.  You haven't
done any of these things.

All of these problems are just changing a fraction to another fraction that's
equivalent but has a different denominator.  Whatever the old denominator
was multiplied by to get the new one, the old numerator also has to be
multiplied by the same thing.  If you don't do that, then you've changed
the value of the fraction.

You have some more work to do.

Nata [24]

A ratio shows us the number of times a number contains another number. The correct option is C.

<h3>What is a Ratio?</h3>

A ratio shows us the number of times a number contains another number.

For winning less than $10, a person needs to take out a green ticket or a yellow ticket. Therefore, the odds against winning less than $10 are,

(Number of blue tickets) : (Number of green and yellow tickets)

5: 30

1: 6

Hence, the correct option is C.
