replace is with the = sign and of with the x (multiplication)sign and wn for what number
wn=4%x31 change the 4% to a decimal (move decimal 2 places to the left = .04)
wn=.04x31
1.24=.04x31
If you were finding % just use the same basic formula and replace what information you have with what your looking for ex: 1.24 is what percent of 31
1.24=wPx31 you have to get your known number on one side and unknown on the other side of the = so you now have 1.24 divided by 31=WP (oppisite of multiplication is division) 1.24/31=.04 change .04 to a percent move decimal 2 places right 4%
And if you were finding the whole 1.24 is 4% of WN
1.24=4% x WN
1.24/.04=31
