Question

show that 21/25 and 35/54 are in their lowest terms.​

Answer 1

$we \: know \: that \: \frac{21}{25} and \: \frac{35}{54} are \: in \: their \: lowest \: term \: or \: reduced \: form \: and \: cannot \: be \: further \: divided \\ \\ mark \: me \: as \: brainliest$

Answer 2

you can represent or prove that they are in the lowest terms by dividing them through different number such as 2,3,5,7 and it will not get divided with any of them. This proves that they are in lowest term because a fraction is in lowest term only when it is not divided by any other number.
