Jessica Said:Algebra Fractions Test Tomorrow Help Please?We Answered:Easiest way ever, depending, would either be to turn them into decimals (sometimes you cannot do this!) Otherwise you have to find a common denominator.
1/2 + 1/3, for example. This would be a bad one to turn into decimals because 1/3 is irrational (it goes on forever as 0.3333...) So a common denominator is the way to go!
the LCM (least common multiple) of 2 and 3 (the denominators) is 6. so 1/2 = 3/6, because to get from 2 to 6 you'd multiply 2 by 3, so do the same for the...

Randall Said:Writing percents as a common fractions/mixed numbers?We Answered:Hello Booker,
A percent is any number divided by one hundred (that's where the % comes from). To write a percent as a number, multiply by one hundred---remember that 1/3 is .3333.
So........422 1/3% is 422.3333%....multiplied by one hundred is 42233.33 (...decimal equivalent...).
To convert a percent to a fraction, you STILL divide by one hundred......
422 1/3 must be converted to an improper fraction....multiply 422 by the three in 1/3 and add the 1 in
1/3.....your improper fraction is....1267/3 (In fraction form, to divide by 100 is to multiply by 1/100.
1267/3 multiplied...

Tracy Said:How do I convert word problems with fractions and decimals into ratios?We Answered:lets say you have the fraction 4/9. the ratio would then be 4:9. The numerator comes first and the denominator comes second. Lets say you have the decimal .5. This means it is 50% or 1/2. Since you know its 1/2, you can make the ratio 1:2. Similar lets say you have .4. This means its 40% or 4/10 or 2/5. That becomes 2:5.Jon Said:Prepare at least four problems on fractions that will be useful in your career/job. Present...

Jimmie Said:what do you do when subtracting fractions if there isnt a number to Borrow?We Answered:with 11/13 - 2/13, you already have a common denominator, just subtract the tops.
11/13 - 2/13 = (11-2)/13 = 9/13
If by 1 and 11/13 you mean the mixed number of 1 + 11/13, then 1 + 11/13 - 1 = 11/13 (the ones cancel).
