Hi!
There are two ways to do this.
1. Start with the first part of the decimal, (4.) then divide 3/7 to get the second part.
3/7 = 0.43
4.43
2. Convert the mixed number 4 3/7 to a fraction.
4 x 7 = 28
28 + 3 = 31
31/7
Now convert that into a decimal.
31/7 = 4.43
The answer is 4.43
Hope this helps! :)
If Bobby claims Peter started with 21 cards, then we'll work this into our equation.
21 - 3 (that he lost) = 18
18 / 2 (the half he gave) = 9
So this means that he did have 21 cards to begin with. Please reply to this with a list of the answers that can/could be checked!
