Question

hello I am having problems doing rounding mixed fractions to whole numbersChange the following mixed numbers to whole numbers:1) 9 5/7, 2) 3 5/6

Answer 1

To change the following mixed number to a whole number, we can proceed as follows:

`9(5)/(7)=9+(5)/(7)`

When we have mixed numbers, we have the sum of an integer and a fraction. Then we need to add both numbers following the rules for adding fractions:

`(a)/(b)+(c)/(d)=(a\cdot d+b\cdot c)/(b\cdot d)`

Now, we can add both numbers above:

`(9)/(1)+(5)/(7)=(9\cdot7+1\cdot5)/(1\cdot7)=\frac{63+5_{}}{7}=(68)/(7)`

We have an improper fraction that is equivalent to the mixed number. In both cases, if we "transform" both numbers to decimals, we will get:

`9+(5)/(7)=9+0.714285714286=9.71428571429`

And

`(68)/(7)=9.71428571429`

If we see the number
