Multiply 3/7 by 9/10
To multiply fractions, you need to multiply the numerators together and then multiply the denominators together.
So, multiply 3/7 by 9/10:
(3/7) x (9/10) = (3 x 9) / (7 x 10)
Simplifying the numerator and denominator:
= 27/70
Multiply 49 by −3. Write the answer as a mixed number in simplest form.
To multiply a whole number by a negative number, you simply multiply the absolute values of the numbers and then add a negative sign to the result.
So, 49 x -3 = -147
To express this as a mixed number in simplest form, we divide -147 by the denominator, which is 1, since we're dealing with a whole number.
Therefore, the answer is -147.
Multiply 9.6 by 0.2. Write the answer as a decimal
To multiply decimals, you can multiply them as if they were whole numbers and then adjust the decimal place in the final answer.
So, multiply 9.6 by 0.2:
9.6 x 0.2 = 1.92
So, the answer is 1.92.
Multiply 2.6 by −1.3.
To multiply decimals, you can multiply them as if they were whole numbers and then adjust the decimal place in the final answer.
So, multiply 2.6 by -1.3:
2.6 x (-1.3) = -3.38
Therefore, the answer is -3.38.
Multiply 37 by 910
To multiply fractions, you multiply the numerators (top numbers) together to get the new numerator, and multiply the denominators (bottom numbers) together to get the new denominator.
So, to multiply 3/7 by 9/10, you will multiply the numerators (3 * 9) and the denominators (7 * 10):
Numerator: 3 * 9 = 27
Denominator: 7 * 10 = 70
Therefore, the product of 3/7 and 9/10 is 27/70.
