Find the quotient of the given fractions below with solutions: 1.) 7/8 divided by 1/60 2.) 1/6 divided by 5/12 3.) 5/12 divided by 1/60 4.) 12/5 divided by 1/6
The Correct Answer and Explanation is:
Let’s work through the division of fractions step by step for each problem. The rule for dividing fractions is to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping its numerator and denominator.
1) 78÷160\frac{7}{8} \div \frac{1}{60}87÷601
To divide 78\frac{7}{8}87 by 160\frac{1}{60}601, we multiply 78\frac{7}{8}87 by the reciprocal of 160\frac{1}{60}601, which is 601\frac{60}{1}160.78×601=7×608×1=4208\frac{7}{8} \times \frac{60}{1} = \frac{7 \times 60}{8 \times 1} = \frac{420}{8}87×160=8×17×60=8420
Now, simplify 4208\frac{420}{8}8420. Divide both the numerator and denominator by 4 (the greatest common divisor):4208=1052\frac{420}{8} = \frac{105}{2}8420=2105
So, the result is 1052\frac{105}{2}2105.
2) 16÷512\frac{1}{6} \div \frac{5}{12}61÷125
To divide 16\frac{1}{6}61 by 512\frac{5}{12}125, multiply 16\frac{1}{6}61 by the reciprocal of 512\frac{5}{12}125, which is 125\frac{12}{5}512.16×125=1×126×5=1230\frac{1}{6} \times \frac{12}{5} = \frac{1 \times 12}{6 \times 5} = \frac{12}{30}61×512=6×51×12=3012
Simplify 1230\frac{12}{30}3012 by dividing both the numerator and denominator by 6:1230=25\frac{12}{30} = \frac{2}{5}3012=52
So, the result is 25\frac{2}{5}52.
3) 512÷160\frac{5}{12} \div \frac{1}{60}125÷601
To divide 512\frac{5}{12}125 by 160\frac{1}{60}601, multiply 512\frac{5}{12}125 by the reciprocal of 160\frac{1}{60}601, which is 601\frac{60}{1}160.512×601=5×6012×1=30012\frac{5}{12} \times \frac{60}{1} = \frac{5 \times 60}{12 \times 1} = \frac{300}{12}125×160=12×15×60=12300
Simplify 30012\frac{300}{12}12300 by dividing both the numerator and denominator by 12:30012=251=25\frac{300}{12} = \frac{25}{1} = 2512300=125=25
So, the result is 252525.
4) 125÷16\frac{12}{5} \div \frac{1}{6}512÷61
To divide 125\frac{12}{5}512 by 16\frac{1}{6}61, multiply 125\frac{12}{5}512 by the reciprocal of 16\frac{1}{6}61, which is 61\frac{6}{1}16.125×61=12×65×1=725\frac{12}{5} \times \frac{6}{1} = \frac{12 \times 6}{5 \times 1} = \frac{72}{5}512×16=5×112×6=572
So, the result is 725\frac{72}{5}572.
Summary of Results:
- 78÷160=1052\frac{7}{8} \div \frac{1}{60} = \frac{105}{2}87÷601=2105
- 16÷512=25\frac{1}{6} \div \frac{5}{12} = \frac{2}{5}61÷125=52
- 512÷160=25\frac{5}{12} \div \frac{1}{60} = 25125÷601=25
- 125÷16=725\frac{12}{5} \div \frac{1}{6} = \frac{72}{5}512÷61=572
The key to these problems is remembering that division of fractions involves multiplying by the reciprocal, which allows us to transform the division operation into a simple multiplication problem.
