To spell number into word, it is best if you group the number by three digit. From the number 43,080,700 you can group it into three groups
1. 700
2. 080
3. 43
The first group of 700 doesn't need to add name so you called it "seven hundred"
The second group will need to add "thousands" so it's "eighty thousand"
The third group is 43 need to add "million" so it is "forty three million"
Then you add them all into forty-three million, eighty thousand seven hundred
The greatest common factor of 49 and 84 is 7
Knowing that line ME and EU and equal, set the equations equal to each other and then solve for M. 6m+5 = 7m so by subtracting 6m from both sides, m=5
