How to Multiply Fractions

The multiplication of fractions is carried out by multiplying numerator by numerator and denominator by denominator, this is the method.

  • In case there is any mixed number - We will convert it into a fraction and then solve according to the learned method.
  • In case there is any whole number - We will convert it into a fraction and then solve according to the learned method.
  • The commutative property works - We can change the order of the fractions within the exercise without altering its result.

Exercise #1

23×57= \frac{2}{3}\times\frac{5}{7}=

Step-by-Step Solution

Let us solve the problem of multiplying the two fractions 23\frac{2}{3} and 57\frac{5}{7}.

  • Step 1: Identify the numerators and denominators. Here, the numerators are 22 and 55, and the denominators are 33 and 77.
  • Step 2: Multiply the numerators: 2×5=102 \times 5 = 10.
  • Step 3: Multiply the denominators: 3×7=213 \times 7 = 21.
  • Step 4: Put the results together in a new fraction: 1021\frac{10}{21}.
  • Step 5: Simplify the fraction if needed. In this case, 1021\frac{10}{21} is already in its simplest form as 1010 and 2121 have no common factors besides 11.

Therefore, the solution to the problem 23×57 \frac{2}{3} \times \frac{5}{7} is 1021\frac{10}{21}.

Answer:

1021 \frac{10}{21}

Exercise #2

14×45= \frac{1}{4}\times\frac{4}{5}=

Step-by-Step Solution

To multiply fractions, we multiply numerator by numerator and denominator by denominator

1*4 = 4

4*5 = 20

4/20

Note that we can simplify this fraction by 4

4/20 = 1/5

Answer:

15 \frac{1}{5}

Exercise #3

14×32= \frac{1}{4}\times\frac{3}{2}=

Step-by-Step Solution

To solve the problem of multiplying the fractions 14\frac{1}{4} and 32\frac{3}{2}, we will follow these steps:

  • Step 1: Multiply the numerators of the fractions.
  • Step 2: Multiply the denominators of the fractions.
  • Step 3: Write the result as a fraction and simplify if needed.

Now, let's work through each step:

Step 1: Multiply the numerators:
The numerators are 11 and 33. Thus, 1×3=31 \times 3 = 3.

Step 2: Multiply the denominators:
The denominators are 44 and 22. Thus, 4×2=84 \times 2 = 8.

Step 3: Write the result as a fraction and simplify:
The resulting fraction is 38\frac{3}{8}. This fraction is already in simplest form.

Therefore, the solution to the problem is 38\frac{3}{8}.

Among the choices provided, the correct answer is choice 3: 38\frac{3}{8}.

Answer:

38 \frac{3}{8}

Exercise #4

34×12= \frac{3}{4}\times\frac{1}{2}=

Step-by-Step Solution

To solve the problem of multiplying the fractions 34 \frac{3}{4} and 12 \frac{1}{2} , follow these steps:

  • Step 1: Multiply the numerators.
    Multiply 3 3 and 1 1 , which gives 3 3 .
  • Step 2: Multiply the denominators.
    Multiply 4 4 and 2 2 , which gives 8 8 .
  • Step 3: Combine the results to form a new fraction.
    This results in 38 \frac{3}{8} .

The fraction 38 \frac{3}{8} is already in its simplest form, so we do not need to simplify further.

Therefore, the solution to the problem is 38 \frac{3}{8} .

Answer:

38 \frac{3}{8}

Exercise #5

16×13= \frac{1}{6}\times\frac{1}{3}=

Step-by-Step Solution

To solve the problem of multiplying two fractions 16 \frac{1}{6} and 13 \frac{1}{3} , we'll follow these steps:

  • Step 1: Multiply the numerators of the fractions.
  • Step 2: Multiply the denominators of the fractions.
  • Step 3: Simplify the resulting fraction if necessary.

Let's apply these steps to our problem:

Step 1: Multiply the numerators: 1×1=1 1 \times 1 = 1 .
Step 2: Multiply the denominators: 6×3=18 6 \times 3 = 18 .

Therefore, the product of 16 \frac{1}{6} and 13 \frac{1}{3} is 118 \frac{1}{18} .

The solution to the problem is 118 \frac{1}{18} , which corresponds to choice 4.

Answer:

118 \frac{1}{18}
