4 1/3 ÷ - 1 1/5

To divide fractions, we need to convert them to improper fractions first.

The mixed number 4 1/3 can be expressed as an improper fraction as: 4 1/3 = (4 * 3 + 1) / 3 = 13/3
The mixed number 1 1/5 can be expressed as an improper fraction as: 1 1/5 = (1 * 5 + 1) / 5 = 6/5

Now we can divide the fractions:

(13/3) ÷ (6/5) = (13/3) * (5/6)

To simplify this, we can cancel out common factors:

(13/3) * (5/6) = (13 * 5) / (3 * 6) = 65/18

Therefore, 4 1/3 ÷ -1 1/5 = 65/18.

−2/17÷−1/2
Responses
A −1/17
B 1/17
C 4/17
D 3/34

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.

Reciprocal of -1/2 is -2/1.

So, we have:

-2/17 ÷ -1/2 = -2/17 * -2/1

Simplifying, we get:

(-2 * -2) / (17 * 1) = 4/17

Therefore, the answer is C) 4/17.

At West High School, 2/5

of the students play a sport. Of the students who play a sport, 1/4
play football. What fraction of the students at West High School play football?

To find the fraction of students who play football, we need to multiply the fractions representing the proportion of students who play a sport and the proportion of sport-playing students who play football.

(2/5) * (1/4) = 2/20

Simplifying, we get:

2/20 = 1/10

Therefore, 1/10 of the students at West High School play football.
