Letโ€™s take an example

Check whether 1/2 , 128/256 are equivalent .

ย 

To check,

ย  we make both fractions equal.

ย  1/2 = 128/256

And then cross multiply

1 ร— 256 = 128 ร— 2

ย ย ย ย ย  256 = 256

Since this is true

ย  1/2, 128/256 are equivalent

ย 

Check whether 1/ 3 , 99 /2 97 are equivalent.

To check,

ย  we make both fractions equal.

ย  ย  1/3 = 99/297

And then cross multiply

Checking whether fractions are equivalent - Part 2

1 ร— 297 = 99 ร— 3

ย ย ย ย ย  297 = 297

ย 

Since this is true

ย 

ย  1/2, 99/297 are equivalent

ย 

Check whether 4 / 5 , 28 / 35 are equivalent.

To check,

ย  we make both fractions equal.

ย  4/5 = 28/35

And then cross multiply

Checking whether fractions are equivalent - Part 3

4 ร— 35 = 28 ร— 5

ย ย ย  140 = 140

ย 

Since this is true.

ย 

ย  4/5, 28/35 are equivalent.

Checking whether fractions are equivalentLetโ€™s take an example Check whether ๐Ÿ/๐Ÿ, ๐Ÿ๐Ÿ๐Ÿ–/๐Ÿ๐Ÿ“๐Ÿ” are equivalent. To check, we make both fractions equal. 1/2 = 128/256 And then cross multiply 1/2 = 128/256 1 ร— 256 = 128 ร— 2 256 = 256 Since this is true 1/2, 128/256 are equivalent Check whether ๐Ÿ/๐Ÿ‘, ๐Ÿ—๐Ÿ—/๐Ÿ๐Ÿ—๐Ÿ• are equivalent. To check, we make both fractions equal. 1/3 = 99/297 And then cross multiply 1/3 = 99/297 1 ร— 297 = 99 ร— 3 297 = 297 Since this is true 1/2, 99/297 are equivalent Check whether ๐Ÿ’/๐Ÿ“, ๐Ÿ๐Ÿ–/๐Ÿ‘๐Ÿ“ are equivalent. To check, we make both fractions equal. 4/5 = 28/35 And then cross multiply 4/5 = 28/35 4 ร— 35 = 28 ร— 5 140 = 140 Since this is true. 4/5, 28/35 are equivalent.
