Answer:
4.64
Explanation:
To simplify mixed numbers you can write them either as a fraction or as a decimal number.
Fraction:
first we need to express both parts of mixed number through the same denominator - 1 has 25/25, so that means 4 has 100/25.
Now we can write that as 100/25 and 16/25, which is (100+16)/25 = 116/25
Decimal number:
This time, we convert this fraction part of a number to decimal. Simply dividing, we get that 16/25 equals 0.64. So 4 and 0.64 is 4.64.
