use properties of operations and rules for multiplying signed numbers to multiply - 2/5 by 3/10 write you answer in simplest form.
To multiply fractions, we can simply multiply their numerators and denominators.
The numerator of the result is -2 times 3, which equals -6.
The denominator of the result is 5 times 10, which equals 50.
Thus, the result of multiplying -2/5 by 3/10 is -6/50.
However, we can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2.
-6/50 simplifies to -3/25.
Therefore, the answer in simplest form is -3/25.
multiply 4 by - 5/8 write the answer as a mixed number in simplest form
To multiply a whole number by a fraction, we can simply multiply the whole number by the numerator of the fraction and keep the denominator the same.
So, 4 multiplied by -5/8 is (4 * -5) / 8 = -20/8.
To write the answer as a mixed number, we need to convert the improper fraction -20/8 to a mixed number.
We can see that -20 is divisible by 8, resulting in -2 and remaining 4.
Therefore, -20/8 is equal to -2 and 4/8.
Since 4/8 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 1/2.
Thus, the answer is -2 1/2 in simplest form.
multiply 6.5 by 0.3. write the answer as a decimal
To multiply decimals, we can ignore the decimal points and perform multiplication as if they were whole numbers.
6.5 multiplied by 0.3 is equal to (65 multiplied by 3) divided by 10.
65 multiplied by 3 is 195.
Dividing 195 by 10 gives us 19.5.
Therefore, the answer is 19.5 as a decimal.
multiply - 19.3 by 6
To multiply a decimal by a whole number, we can simply ignore the decimal point and perform multiplication as if they were whole numbers.
-19.3 multiplied by 6 is equal to -116.8.
Therefore, the answer is -116.8.
multiply - 2/ 1/2 by - 1/ 3/5 write answer as a decimal
To multiply fractions, we can multiply their numerator by numerator and denominator by denominator (also known as "cross-multiplication").
First, let's simplify the problem:
-2 / (1/2) * -1 / (3/5)
Since dividing by a fraction is equivalent to multiplying by its reciprocal, we can rewrite the expression as:
-2 * (2/1) * -5/3
Multiplying the numerators and the denominators, we get:
(-2 * 2) / (1 * 1) * (-5 * 1) / (3 * 1) = 4 / 1 * - 5 / 3 = -20 / 3
To write this fraction as a decimal, we divide the numerator by the denominator:
-20 ÷ 3 ≈ -6.6667 (rounded to four decimal places)
Therefore, the answer as a decimal is approximately -6.6667.
To multiply signed numbers, you multiply their absolute values and use the following rules for the product's sign:
1. If both numbers have the same sign (positive or negative), the product is positive.
2. If the numbers have different signs (one positive and one negative), the product is negative.
In this case, we need to multiply -2/5 by 3/10.
Step 1: Find the absolute values of the numbers: |-2/5| = 2/5 and |3/10| = 3/10.
Step 2: Multiply the absolute values: (2/5) * (3/10) = 6/50.
Step 3: Determine the sign of the product. Since -2/5 is negative and 3/10 is positive, the product will be negative.
Therefore, the product of -2/5 and 3/10 is -6/50.
To write the answer in simplest form, we can simplify the fraction:
-6/50 = (-3 * 2) / (2 * 5 * 5) = -6/100.
We can further simplify by dividing the numerator and denominator by their greatest common divisor, which is 2:
-6/100 = (-3/50).
So the answer, in simplest form, is -3/50.
