Find the missing number.
5/15 = ?/3
Is 1 the correct answer?
5 / 15 = x / 3
5 * 3 = x * 15
15 = 15 x Divide both sides with 15
x = 1
5 / 15 = 1 / 3
I got the answer 1 by doing this...
15 divided by 3 = 5
5 divided by 5 = 1
Is that a wrong way to answer the problem?
That's the way my book shows.
That's the way I got the answer too. Thank you!!!
To find the missing number in the equation 5/15 = ?/3, we can set up a proportion.
First, cross multiply the fractions: 5 * 3 = 15 * ?.
This simplifies to 15 = 15 * ?.
Next, divide both sides of the equation by 15 to solve for the missing number:
15 / 15 = ? / 15.
Since anything divided by itself equals 1, we have ? = 1.
Therefore, the missing number in the equation is indeed 1.
