Solve Mixed Number Division: 6⅞ ÷ 6½ Step-by-Step

Question

(+689):(+612)= (+6\frac{8}{9}):(+6\frac{1}{2})=

Video Solution

Step-by-Step Solution

Since we are dividing two positive numbers, the result must be a positive number:

+:+=+ +:+=+

First, let's convert each mixed number to an improper fraction as follows:

689=6×9+89=54+89=629 6\frac{8}{9}=\frac{6\times9+8}{9}=\frac{54+8}{9}=\frac{62}{9}

612=6×2+12=12+12=132 6\frac{1}{2}=\frac{6\times2+1}{2}=\frac{12+1}{2}=\frac{13}{2}

Now we have the problem:

629:132= \frac{62}{9}:\frac{13}{2}=

Let's convert the division to multiplication, and don't forget to swap the numerator and denominator:

629×213= \frac{62}{9}\times\frac{2}{13}=

Let's combine everything into one problem:

62×29×13= \frac{62\times2}{9\times13}=

Let's solve the multiplication in the numerator, and factor the denominator into an addition problem as follows:

1249×10+9×3= \frac{124}{9\times10+9\times3}=

Let's solve the multiplication problems in the denominator:

12490+27= \frac{124}{90+27}=

Let's combine the denominator and we get:

124117 \frac{124}{117}

Answer

124117 \frac{124}{117}
