Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?

2 4/36

Step-by-step explanation:

To do this, multiply the whole number by the denominator and add it to the numerator.

8 x 9 = 72

72 + 4 = 76

76/9

Then multiply across (multiply numerators with numerators; denominators with denominators)

76 x 1 = 76

9 x 4 = 36

76/36 = 2  4/36

A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.

1/4 x 8/1 = 8/4 = 2

1/4 x 4/9 = 4/36

 = 2  4/36

4b. is 1/3 of an hour per mile

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
