Find the missing number
2/5 = /20
could you explain the steps I take to find the answer
you need to divide 5 by 20.
Then with the number that you get you multiply 2 (the numerator).
That is your answer.
The reason that you take those steps is because whatever you do to the denominator you have to do to the numerator.
5*4 = 20 which is your denominator. Then, you take the numerator(2) and multiply that by four because whatever you do to the bottom, you do to the top. 2*4= 8. The answer is 8/20 which simplifies to 2/5.
5 and 20 are dinominators
To find the missing number in the equation 2/5 = /20, you can use cross multiplication.
Here are the steps to follow:
1. Start by writing down the equation: 2/5 = /20
2. Cross multiply by multiplying the numerator of the first fraction by the denominator of the second fraction and vice versa.
So, 2 * 20 = 5 * x
This simplifies to 40 = 5x.
3. To solve for x, divide both sides of the equation by 5.
40/5 = x
This simplifies to 8 = x.
4. Therefore, the missing number is 8, and the complete equation is: 2/5 = 8/20.
By using the method of cross multiplication, you can solve for the missing number in this type of equation.
