6.371 as a fraction or mixed number

Well I would write this as a fraction. :D
.1 is equal to 1/10 and .1and .10 is equal to 10/100 
so the amount of zeros on the bottom = the amount of numbers past the decimal point.
so you would have

then you multiply the whole number by the denominator, and add it to the numerator


now you put that number over the original denominator.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
