Multiply 4/9 by −3. Write the answer as a mixed number in simplest form.
To multiply a fraction by a whole number, we multiply the numerator of the fraction by the whole number.
To calculate -3 times 4/9, we have:
-3 * 4/9 = -12/9
To simplify this fraction to its simplest form, we divide the numerator and denominator by their greatest common divisor, which is 3:
-12/9 ÷ 3/3 = -4/3
Therefore, the answer as a mixed number in simplest form is -1 1/3.
To calculate -3 times 4/9, we have:
-3 * 4/9 = -12/9
To simplify this fraction to its simplest form, we divide the numerator and denominator by their greatest common divisor, which is 3:
-12/9 ÷ 3/3 = -4/3
Therefore, the answer as a mixed number in simplest form is -1 1/3.
Multiply 2/3 by 1 1/4. Write the answer in simplest form.
To multiply a fraction by a mixed number, we need to convert the mixed number into an improper fraction.
Let's convert 1 1/4 into an improper fraction:
1 1/4 = (4 * 1 + 1)/4 = 5/4
Now we can multiply 2/3 by 5/4:
(2/3) * (5/4) = (2 * 5) / (3 * 4) = 10/12
To simplify this fraction further, we can divide the numerator and denominator by their greatest common divisor, which is 2:
10/12 ÷ 2/2 = 5/6
Therefore, the answer in simplest form is 5/6.
Let's convert 1 1/4 into an improper fraction:
1 1/4 = (4 * 1 + 1)/4 = 5/4
Now we can multiply 2/3 by 5/4:
(2/3) * (5/4) = (2 * 5) / (3 * 4) = 10/12
To simplify this fraction further, we can divide the numerator and denominator by their greatest common divisor, which is 2:
10/12 ÷ 2/2 = 5/6
Therefore, the answer in simplest form is 5/6.
Multiply 9.6 by 0.2. Write the answer as a decimal.
To multiply decimals, we simply multiply them just like whole numbers, disregarding the decimal points. However, we'll count the total number of decimal places from both numbers to determine the decimal places in the final answer.
In this case, we have 9.6 multiplied by 0.2.
9.6 * 0.2 = 1.92
Therefore, the answer as a decimal is 1.92.
In this case, we have 9.6 multiplied by 0.2.
9.6 * 0.2 = 1.92
Therefore, the answer as a decimal is 1.92.
Multiply 2.6 by −1.3.
To multiply decimals, we follow the same rules as multiplying whole numbers, but we take into account the decimal places in the final answer.
In this case, we have 2.6 multiplied by -1.3.
2.6 * -1.3 = -3.38
Therefore, the answer is -3.38.
In this case, we have 2.6 multiplied by -1.3.
2.6 * -1.3 = -3.38
Therefore, the answer is -3.38.
Use properties of operations and rules for multiplying signed numbers to multiply −2/5 by 3/10. Write the answer in simplest form.(1 point)
To multiply fractions, we multiply the numerators and the denominators. However, since we have signed numbers, we also need to consider the signs.
In this case, we're multiplying -2/5 by 3/10.
The sign of the product will be negative because we have one negative fraction and one positive fraction.
(-2/5) * (3/10) = (-2 * 3) / (5 * 10) = -6/50
To simplify this fraction further, we can divide the numerator and denominator by their greatest common divisor, which is 2:
-6/50 ÷ 2/2 = -3/25
Therefore, the answer in simplest form is -3/25.
In this case, we're multiplying -2/5 by 3/10.
The sign of the product will be negative because we have one negative fraction and one positive fraction.
(-2/5) * (3/10) = (-2 * 3) / (5 * 10) = -6/50
To simplify this fraction further, we can divide the numerator and denominator by their greatest common divisor, which is 2:
-6/50 ÷ 2/2 = -3/25
Therefore, the answer in simplest form is -3/25.
