49 and 63 can both be divided by 7
49/7=7
63/7= 9
7/9
Let X be the first and second number.
X+X = 18
+ X-X = 2
2X = 20 (divide both sides by 2
X = 10
Substitute the values to get the second number
10+X = 18
X = 18 -10
X = 8
Therefore, the numbers are 10 and 8
You multiply the whole number and multiply the denominator (the bottom one of the fraction) then you take the product and add the numerator (the top one of the fraction). That's how you get an improper fraction. Then once you get and improper fraction, you divide the numerator and denominator by their common factors. That's how you simply a mixer number.
