Answer:
D. 6 21/50
Explanation:
In order to find a fraction in lowest terms, we first have to actually change the number 6.42 into a fraction.
0.42 can also be written as the fraction 42/100.
To simplify the fraction, we just have to look for a number that both the number on the top (numerator) and number on the bottom (denominator) can be divided by.
Well, both 100 and 42 can be divided by 2.
100 divided by 2 = 50
42 divided by 2 = 21
Now we have the fraction 21/50
21 and 50 do not have a number they can both be divided by, so it is in lowest terms.
Now, just add it back to 6.
6 21/50
