MOA

Need clarification. If a scope say that 1 click =1/4"@100 yards, 1 click=1/2@ 200 yrds. If you are zeroed @ 100 yrds and the bullet drop is 2" at 200 yrds you would move the the cross hairs up 4 clicks. If it drops 5" at 300yrds you would move up 4 clicks being 3/4 x 5 = 3.75. Is this right or wrong.

You have to DIVIDE by the "per click" amount, not multiply.

It's 3/4" per click at 300, that means one click is 3/4, 2 is 1 1/2, 3 is 2 1/4, 4 is 3, 5 is 3 3/4, 6 is 4 1/2, 7 is 5 1/4....

or, 5 divided by 3/4, which is the same as (5 times 4) divided by 3, which is 20/3, which is 6.666 clicks..... 7 clicks...

To divide by a fraction, you flip the fraction, multiply by the top number and divide by the bottom.

5 divided by 3/4s is 5x4/3
