Answer: sixty six fifty fourths
30/54 + 36/54 = 66/54
Step-by-step explanation: Find a common denominator
Here, it looks like we can multiply the 9 × 6 to get 54
Then we divide the original denominator into the common denominator, then multiply the numerator by the quotient to get an equivalent fraction to add.
Starting with the 5/9 54÷9 = 6 The quotient, 6 multiplies by the numerator 5
6 × 5 = 30 That is the new numerator.
30/54 is the equivalent fraction for 5/9
Now 4/6 54÷6 = 9 Multiply this quotient, 9 times the numerator 4
9 × 4 = 36 That is the new numerator
36/54 is the equivalent fraction for 4/6
Add the numerators of the equivalent fractions keep the denominator the same:
30/54 + 36/54 = 66/54
It is possible to simplify this process. 4/6 is equivalent to 2/3 or 6/9
We could add 5/9 + 6/9 to get 11/9
66 and 54 are both divisible by 6, so 66/54 can be simplified to 11/9 or the mixed number 1²/₉
