Accepted Solution

A:
What is 21/39 Divided by 31/17?MethodsBreaking down the problem:First, let’s break down each piece of the problem, as each piece is important. We have the first fraction, or the dividend, which can be broken down into its numerator, 21, and its denominator, 39. We also have the second fraction, or the divisor, which can be broken down into its numerator, 31, and its denominator, 17:Numerator of the dividend: 21Denominator of the dividend: 39Numerator of the divisor: 31Denominator of the divisor: 17So, what is 21/39 divided by 31/17? Let’s work through the problem, and find the answer in both fraction and decimal forms.What is 21/39 Divided by 31/17, Step-by-stepFirst let’s set up the problem:2139÷3117\frac{21}{39} ÷ \frac{31}{17}3921​÷1731​Step 1:Interestingly, the first step to solving a division problem between two fractions is to multiply. First, you multiply the numerator of the dividend, 21, by the denominator of the divisor, 17.21 x 17 = 357This will become the numerator of the answer.Step 2:Then, multiply the denominator of the dividend, 39, by the numerator of the divisor, 31:39 x 31 = 1209This will be the denominator of the answer.Step 3:Put the two answers together into one fraction, and this will be the answer to the problem in fraction form:3571209\frac{357}{1209}1209357​ = 119403\frac{119}{403}403119​To display the answer to 21/39 divided by 31/17 in decimal form, you can continue to divide the numerator of the answer, 357, by the denominator, 1209. The answer can be rounded to the nearest three decimal points, if needed:3571209=0.295\frac{357}{1209}= 0.2951209357​=0.295So in decimal form, 21/39 divided by 31/17 = 0.295And in fractional form, 21/39 divided by 31/17 is 119/403Practice Other Division Problems Like This OneIf this problem was a little difficult or you want to practice your skills on another one, give it a go on any one of these too!What is 20/10 divided by 25?1 divided by what equals 13?What divided by 32 equals 36?What is 12/8 divided by 6/5?What is 84 divided by 16/17?
