12/42
We note that both numbers are even, and so will cancel down (divide) by '2'.
Hence
12/42 = 6/21
Again we note that both numbers are multiples of '3'. So cancel down by '3'
Hence
6/21 = 2/7
2/7 will not cancel down any further as both '2' and '7' are prime numbers.
Hence 12/42 = 2/7
NB Fluency with your multiplication tables is critical for this method.
12|42 / 6|6 = 2|7
42/48 = 7/8
No. You cannot simplify this fraction.
It is: 1/6
It is 88/100, which you can simplify if you so wish.
To simplify a fraction, divide both the top number (numerator) and bottom number (denominator) in the fraction by the SAME number. In this case, we will divide both the top and the bottom by 6. 42 / 6 = 7 60 / 6 = 10 Therefore 42/60 in its simplest form is 7/10.
42/48 = 7/8
18/42 = 3/7
42 and 5 are co-prime so the fraction cannot be simplified.

No. You cannot simplify this fraction.
Expressed as a proper fraction in its simplest form, by dividing the numerator and denominator by 6, 36/42 is equal to 6/7 or six sevenths.
0.42 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. Its equivalent, in rational form, is 42/100. You can simplify this rational fraction if you require.
