385:121=
To solve this problem, we need to proceed through the following steps:
- Step 1: Convert the mixed numbers to improper fractions.
- Step 2: Divide the improper fractions using multiplication by the reciprocal.
- Step 3: Simplify the resulting fraction and convert back to a mixed number.
Now, let's work through each step:
Step 1: Convert
For 385, multiply the whole number 3 by the denominator 8 and add the numerator 5:
3×8+5=24+5=29
<=> This gives us the improper fraction 829.
For 121, multiply the whole number 1 by the denominator 2 and add the numerator 1:
1×2+1=2+1=3
<=> This gives us the improper fraction 23.
Step 2: Divide the improper fractions.
829÷23 becomes 829×32.
Multiply the numerators and the denominators:
8×329×2=2458.
Step 3: Simplify the resulting fraction.
Divide both the numerator and the denominator by their greatest common divisor, which is 2:
24÷258÷2=1229.
Convert 1229 into a mixed number:
29÷12=2 remainder 5
Thus, it becomes 2125.
Therefore, the division of 385 by 121 yields 2125.
