Answer:
4.2
Step-by-step explanation:
Whenever we are dividing by 10, we just shift the decimal point by one digit to the right.
In the number 42 the place of the deimcal point is obvious when we write 42.0. If we now divide 42 by 10 then we just shiftthe decimal point by one digit to the left. Doing this gives
42.0 / 10 = 4.20 or 4.2
Hence,
42 / 10 = 4.2
To get to a fractional form, we first do the normal division.
The remainder is 2.
The divisior is 10.
The quoteint is 4.
Therefore,
42 / 10 = quotient + remainder / divisor
therefore,
42 / 10 = 4 + 2 / 10
since 2 / 10 = 1 / 5
we have
42 / 10 = 4 + 1/5
