Tell which property allows you to compare
`2/3 xx [3/4 xx 5/7]` and `[2/3 xx 5/7] xx 3/4`
उत्तर
`2/3 xx [3/4 xx 5/7] = 2/3 xx (5/7 xx 3/4)` ...[By commutative property over multiplication]
= `(2/3 xx 5/7) xx 3/4` ...[By associative property over multiplication]
Hence, `2/3 xx (3/4 xx 5/7)` can be compared with `(2/3 xx 5/7) xx 3/4` with the help of associative and commutative property.
