If two ratios have the same value when simplified, then they are called Equivalent Ratios.
Equivalent ratios can be obtained by multiplying or dividing both sides by the same non-zero number.
As we want 3 equivalent ration in higher terms we will multiply it
4 : 7
by multiply with 2
4* 2 : 7* 2
8 : 14
by multiply with 3
4* 3 : 7* 3
2 : 21
by multiply with 4
4* 4 : 7* 4
16 : 28
you can multiply with any nonzero number
Hope this helped!
Have a great day!
