A fraction that is greater than 1 is a fraction whose numerator is larger than its denominator, this type of fractions can be converted into mixed numbers.
It is important that we remember similar topics:
Multiply the whole number by the denominator.
To the obtained product, add the numerator. The final result will be the new numerator.
Nothing is changed in the denominator.
The whole number is written in the numerator and the 1 in the denominator.
You can continue reading in these articles:
\( 8\times\frac{5}{9}= \)
To add and subtract mixed numbers, we will act as follows:
We will convert mixed numbers into fractions - fractions with numerator and denominator that do not have whole numbers.
We will find a common denominator (usually by multiplying the denominators).
We will add or subtract only the numerators. The denominator will be written only once in the final result.
We will solve the multiplication of an integer by a fraction and by a mixed number in the following way:
\( 3\times\frac{8}{12}= \)
\( 10\times\frac{7}{9}= \)
\( 7\times\frac{6}{8}= \)
We will convert the whole numbers and mixed numbers to fractions and rewrite the exercise.
We will multiply the numerators and the denominators separately.
The product of the numerators will be written in the new numerator.
The product of the denominators will be written in the new denominator.
Solve:
\( 7\times\frac{3}{8}= \)
\( 8\times\frac{1}{2}= \)
\( 3\times\frac{6}{7}= \)
We will convert mixed numbers to fractions and rewrite the exercise.
We will multiply the numerators and the denominators separately.
The product of the numerators will be written in the new numerator.
The product of the denominators will be written in the new denominator.
โข The commutative property works - We can change the order of the fractions within the exercise without altering the result.
We will convert mixed numbers to fractions and rewrite the exercise.
We will convert the division into multiplication and swap between the numerator and the denominator in the second fraction.
We will solve by multiplying numerator by numerator and denominator by denominator.
\( 7\times\frac{2}{5}= \)
\( 6\times\frac{3}{4}= \)
\( 2\times\frac{5}{7}= \)
We will convert the division into multiplication and swap between the numerator and the denominator in the second fraction.
We will solve by multiplying numerator by numerator and denominator by denominator.
To solve the problem of multiplying by , we can follow these steps:
Therefore, the solution to the multiplication problem is .
To solve this problem, we'll pursue a step-by-step method:
Let's proceed with these steps:
Step 1: Simplify :
.
Step 2: Multiply the integer by the fraction:
.
Thus, the result of the multiplication is .
To solve the problem , we follow these steps:
Let's work through each step:
Step 1: Multiply 10 by 7 to get 70.
Step 2: Divide 70 by 9 to get 7 remainder 7.
Step 3: The proper whole number from the division is 7, with the remainder over the original fraction denominator giving us the final fraction .
Thus, the product is .
To solve the multiplication of an integer with a fraction, we need to follow these steps:
Now, let's work through each step:
Step 1: Multiply 7 by 6, which gives us as the numerator.
Step 2: The denominator remains 8, so we have the fraction .
Step 3: Simplify by finding the greatest common divisor (GCD) of 42 and 8. The GCD is 2.
We divide the numerator and the denominator by 2: .
Step 4: Convert into a mixed number:
Divide 21 by 4, which equals 5 with a remainder of 1. Thus, is equivalent to the mixed number .
Therefore, the solution to the problem is .
Solve:
To solve this problem, we will start by multiplying the whole number 7 by the fraction using the rule for multiplying a whole number by a fraction.
Calculate the product:
The fraction is an improper fraction, meaning the numerator is greater than the denominator. To convert it to a mixed number, we divide 21 by 8:
The remainder becomes the numerator of the fraction part, and the denominator remains the same as in the original fraction.
Therefore, the solution to the problem is .
\( 4\times\frac{2}{3}= \)
\( 3\times\frac{1}{2}= \)
\( 2:\frac{2}{3}= \)
