math. HOW DO I CONVERT A DECIMAL TO A FRACTION
how do i convert a decimal to fraction in SIMPLEST FORM? a) -2.756 ?? Write out the 0.756 as 756/1000, then reduce it to lower terms if you can. Since both numerator and denominator are evenly divisible by 4, 756/1000 can be reduced to 189/250. The mixed number becomes -2 189/...

I also need help with this one: Add. Express answer in simplest form. ((8)/(s))+ ((8)/(s^2)) (8s + 8)/s^2 = 8(s+1)/s^2 That isn't much simpler than the original form, but sometimes they want single denominators. wouldn't it be : (8s+8)/s^2

write in simplest form 1/10 / 1/4 they way you typed the problem illustrates well why it is so important to use brackets to show the precise order of operation. I will assume you meant (1/10) ÷ (1/4), if so then it would be (1/10)(4/1) =2/5

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
