(2.5)(-1.3)
-3.25
-2/17 divide by -1/2
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.
So, (-2/17) ÷ (-1/2) is equivalent to (-2/17) * (2/-1).
Now, we can simplify the expression:
(-2/17) * (2/-1) = (-2 * 2) / (17 * -1) = -4 / -17 = 4/17.
Therefore, (-2/17) ÷ (-1/2) simplifies to 4/17.
-4.32 x -1.25
To multiply two negative numbers, you multiply them together and the result will be positive.
(-4.32) x (-1.25) = 5.4
-70.55 divide by (0.5)
To divide a number by a fraction, we multiply the number by the reciprocal of the fraction.
So, -70.55 ÷ (0.5) is equivalent to -70.55 * (2/1).
Now, we can simplify the expression:
-70.55 * (2/1) = -141.10.
Therefore, -70.55 ÷ (0.5) simplifies to -141.10.
4 1/3÷−1 /1/5
Find the quotient above.
To divide a mixed number by a fraction, we first convert the mixed number into an improper fraction.
4 1/3 can be written as (4*3 + 1)/3 = 13/3.
Now, we can rewrite the division expression as a multiplication by the reciprocal of the second fraction:
(13/3) ÷ (-1/1/5)
This is the same as (13/3) * (-1/(1/5)), which is equal to (13/3) * (-5/1).
Multiplying the numerators and denominators, we get:
(13 * -5) / (3 * 1)
-65 / 3
Therefore, the quotient of 4 1/3 ÷ −1 /1/5 is -65/3.
