Svetllana [295]

Answer:

14/11

Step-by-step explanation:

Put the 3 into the one half by multiplying the 3 by the denominator. So now you have -7/2.

Then, make a common denomitator of 4, so you multiply top and bottom of fraction by 2 to get -14/4

Then, divide both sides of the equation by -11/4, and to do this, just multiply by the reciprocal of -4/11

-14/4 x -4/11 = 56/44

Simplify and get 14/11

if the HCF of 408 and 1032 is expressible in the form of 1032 into 2 + 408 into P then find the value of p​
alexandr1967 [171]

Answer:

below.

Step-by-step explanation:

408 = 2*2*2*3*17

1032 = 2*2*2*3*43

So the HCF is 2*2*2*3 = 24

24 = 2/1032 + p/408

24 - 2/1032 = p/408

p = (24 - 2/1032) * 408

p = 9791.21 to nearest hundredth.
