.(1 point)
The product of 3/7 and 9/10 is (3/7) * (9/10) = (3*9) / (7*10) = 27/70.
To multiply 2/3 by 1 1/4, we need to convert the mixed number 1 1/4 into an improper fraction.
1 1/4 = (4*1 + 1) / 4 = 5/4
Now we can multiply:
(2/3) * (5/4) = (2*5) / (3*4) = 10/12
To simplify the fraction, we can divide both the numerator and denominator by their greatest common factor, which is 2:
10 ÷ 2 / 12 ÷ 2 = 5/6
So, the answer in simplest form is 5/6.
Multiply 4/9 by −3. Write the answer as a mixed number in simplest form.(1 point)
To multiply 4/9 by -3, we can multiply the numerators and denominators:
(4/9) * (-3) = (4 * -3) / 9 = -12/9
To express -12/9 as a mixed number, we need to divide the numerator by the denominator:
-12 ÷ 9 = -1 remainder -3
Therefore, the answer is -1 and -3/9 as a mixed number in simplest form. We can simplify the fraction -3/9 by dividing both the numerator and denominator by their greatest common factor, which is 3:
-3 ÷ 3 / 9 ÷ 3 = -1/3
So, the answer as a mixed number in simplest form is -1 1/3.
