Ratios and proportions
RATIOS AND PROPORTIONS x 3 - = - 4 2 The boards don't post spacing as we would wish. I suppose the problem is x/4 = 3/2. Multiply left and right sides by 4. That will "cancel" the 4 in the denominator of the left side. Now multiply both sides by 2. That will "cancel" the 2 in ...

how would i write this ratio in simplest form? 30 seconds to 5 minutes in ratios you should have the same units, then they will cancel and you don't have to write them so how many seconds are there in 5 minutes? your simple ratio is then found: 30sec/300sec = 1/10 or 1:10
