What is 8/15÷2/5?What so u think is the best answer for this problem??
Mademuasel [1]

Answer:

1 1/3

Step-by-step explanation:

Solve. Change the division sign into a multiplication, and flip the second fraction:

(8/15)/(2/5) = (8/15) x (5/2)

Multiply across:

(8 x 5)/(15 x 2) = (40)/(30)

Simplify. Divide common factors:

(40/30)/(10/10) = 4/3

4/3 or 1 1/3 is your answer.

What is 7 7/9 divided by 4/7
e-lub [12.9K]

Answer:

4 44/49

Step-by-step explanation:

7 7/9 is 70/9

then u use 70/9 multiply by 7/4(I call it keep, change, flip method for division of fraction)

You keep the 1st fraction and because it is a mixed fraction, changing it to improper fraction is easier to solve it later on.

after that, you change the division sign to multiply sign(÷ to ×)

then you flip the 2nd fraction, which means 7/4 becomes 4/7

So overall it becomes 60/7 × 4/7 =240/49,4 44/49 as a mixed fraction.

Answer is 4 44/49

Cos(-170°) = _____<br><br> -cos10°<br> cos10°<br> cos(-10°)
Lera25 [3.4K]

Answer:

<h3>-cos10°</h3>

Step-by-step explanation:

cos is positive at first and fourth quadrant

so, cos (-x) = cos (x)

also, cos(180-x) = -cos x

        cos (180+x) = -cos x

cos (-170°) = cos (170°)

cos(170°) = cos (180° - 10°)

              =  - cos 10°
