1,2,4,5,10,20 2x20=40 3x20=60 4x20=80 5x20=100 6x20=120 7x20=140 8x20=160 9x20=180 10x20=200
The first 5 common multiples are: 7x20 = 140 2x7x20 = 280 3x7x20 = 420 4x7x20 = 560 5x7x20 = 700
you can do the traditional multiplication 23 x 7= or you can use the distributive property 7x20=? and 7x3=? add them together to get 161 You always have the choice of doing it by calculator or by pencil.
It may work but it is not normally recommended because the shock from a pellet rifle is different from a regular firearm and it been known to jar loose the glass in a rimfire scope mounted on a pellet rifle.
61/5 + 13/4 = 6x5+1/5 + 1x4+3/4 = 31/5 + 7/4 = 31x4/5x4 + 7x5/4x5 = 124/20 + 35/20 = 159/20 = 7x20+19/20 = 719/20
