Solve Mixed Number Division: 2⅐ ÷ ¼ Step-by-Step

Question

+217:+14= +2\frac{1}{7}:+\frac{1}{4}=

Video Solution

Step-by-Step Solution

Let's convert 2 and seven-sevenths to a simple fraction:

217=2+17=2×77+17=2×77+17=147+17=14+17=157 2\frac{1}{7}=2+\frac{1}{7}=2\times\frac{7}{7}+\frac{1}{7}=\frac{2\times7}{7}+\frac{1}{7}=\frac{14}{7}+\frac{1}{7}=\frac{14+1}{7}=\frac{15}{7}

Now the exercise we received is:

157:14= \frac{15}{7}:\frac{1}{4}=

Let's convert the division exercise to a multiplication exercise, and don't forget to switch the numerator and denominator in the second fraction:

157×41= \frac{15}{7}\times\frac{4}{1}=

Let's combine into one multiplication exercise:

15×47×1=607 \frac{15\times4}{7\times1}=\frac{60}{7}

Let's factor 60 into an addition exercise:

56+47= \frac{56+4}{7}=

Let's separate the exercise into addition between fractions:

567+47= \frac{56}{7}+\frac{4}{7}=

Let's solve the first fraction exercise and we get:

8+47=847 8+\frac{4}{7}=8\frac{4}{7}

Answer

847 8\frac{4}{7}
