divide - 3/17 by -2/3
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and the denominator.
So, to divide -3/17 by -2/3, we can rewrite it as:
-3/17 ÷ -2/3
Reciprocal of -2/3 is -3/2.
Now we have:
-3/17 x -3/2
Multiplying the numerators and denominators, we get:
(-3) x (-3) / (17) x (2)
Simplifying, we have:
9 / 34
Therefore, -3/17 ÷ -2/3 equals 9/34.
So, to divide -3/17 by -2/3, we can rewrite it as:
-3/17 ÷ -2/3
Reciprocal of -2/3 is -3/2.
Now we have:
-3/17 x -3/2
Multiplying the numerators and denominators, we get:
(-3) x (-3) / (17) x (2)
Simplifying, we have:
9 / 34
Therefore, -3/17 ÷ -2/3 equals 9/34.
find the product
4/7(- 20/2)
4/7(- 20/2)
To find the product of two fractions, we simply multiply the numerators together and then multiply the denominators together.
In this case, the product of 4/7 and -20/2 can be calculated as follows:
(4/7) x (-20/2)
Multiplying the numerators (4 x -20) and the denominators (7 x 2), we get:
-80/14
This fraction can be simplified by finding the greatest common divisor. In this case, the greatest common divisor of 80 and 14 is 2.
Dividing the numerator and denominator by 2, we get:
(-80/14) ÷ 2 = -40/7
Therefore, the product of 4/7 and -20/2 is -40/7.
In this case, the product of 4/7 and -20/2 can be calculated as follows:
(4/7) x (-20/2)
Multiplying the numerators (4 x -20) and the denominators (7 x 2), we get:
-80/14
This fraction can be simplified by finding the greatest common divisor. In this case, the greatest common divisor of 80 and 14 is 2.
Dividing the numerator and denominator by 2, we get:
(-80/14) ÷ 2 = -40/7
Therefore, the product of 4/7 and -20/2 is -40/7.
