Let’s take an example
Check whether 1/2 , 128/256 are equivalent .
To check,
we make both fractions equal.
1/2 = 128/256
And then cross multiply
1 × 256 = 128 × 2
256 = 256
Since this is true
1/2, 128/256 are equivalent
Check whether 1/ 3 , 99 /2 97 are equivalent.
To check,
we make both fractions equal.
1/3 = 99/297
And then cross multiply
1 × 297 = 99 × 3
297 = 297
Since this is true
1/2, 99/297 are equivalent
Check whether 4 / 5 , 28 / 35 are equivalent.
To check,
we make both fractions equal.
4/5 = 28/35
And then cross multiply
4 × 35 = 28 × 5
140 = 140
