Simplifying the fraction.
Whenever there is the same number in the numerator and the denominator, you can cancel both. If the numbers are different, but have a common factor, you can replace each number by its factors, and cancel some of the factors. When nothing is left on the top or on the bottom, you replace by the number 1 - one being the identity element of multiplication.
By dividing the numerator and denominator by their HCF
im pretty sure all u do is use a proportion
To simplify a fraction like this you need to identify any common factors between top and bottom. In this case, both are even, so we can divide by 2. Doing this gives 462/1596. These are still both even, so we can divide by 2 again, giving 231/798. Both of these have a digit sum that can divide by 3, so we can divide top and bottom by 3. Doing this gives 77/266. Both top and bottom can divide by 7. Doing this gives 11/38. There are no more common factors, and so we've reached the fraction's simplest form.
160/250 Cancel down by '10' 16/25 This will not cancel down any further as there are no common factors between '16' & 25'.
Divide the percentage by 100. Then reduce to its simplest form (cancel out any common factors between the numerator and the denominator).
No, it is quite possible for the fractions not to have common factors, even if you cross-cancel.
Factor the numerator and denominator, and then cancel any common factors.
In order to multiply fractions with variables, factor all numerators and denominators completely. Use the rules for multiplying and dividing fractions, cancel any common factors, and leave your final answer in factored form.

It is quickest to cancel first. In 4/7 x 5/8 we can cancel the 4 and 8 making 1/7 x 5/2 = 5/7 If nothing will cancel, simply multiply top two numbers for numerator and bottom two for denominator.
By dividing the numerator and denominator by their HCF
Fractions can be simplified when the numerator and denominator have a common factor in them. If both the numerator and denominator have common factors, then we can cancel these factors out. So the simplest for of 18/56 is 9/28.

by dividing or multiplying the numerator and the denominator of a fraction with the same numberex:* 1/2 = (1 x 5)/(2 x 5) = 5/10(multiples both numerator and denominator with 5)1/2 and 5/10 are equivalent fractions* 14/35 = (14:7)/(35:7) = 2/5(divide both numerator and denominator with common factor of 14 and 35)14/35 and 2/5 are equivalent fractions
