simplyfing an an addition of two fractions

you have to type two short tricks to crack age problems and go to 10:17 in the timer
 
i don't like his method because it is not consistent, but I was left with a doubt about the 8 that he came up with when solving for the second problem
 
Revisit this thread you made earlier today, and see why you're wrong. You made the same mistake I told you to fix with the exact same expression. The video might be right, but you wrote it here incorrectly.

what to do to get rid of a fraction in the denominator?

&& Hi, I was wondering if what i have done here is correct 2(5/3 - 1) + 2(7/5-1) / 5/3 -7/52(2/3) + 2(2/5)/ 4/15 my question is , can I do this to get trid of the 4/15 i nthe denominator, that is, multiply the numerator by the multiplicative inverse of the fraction in the denominator? 2(2/3) +...

ohhh, (1/3 + 1/5) * 15=8/15 * 5
hey BBB, where is the glitch, buddy?

(4/3 + 4/5) = 4(1/3+1/5). The method that the used is called factoring.
Now (4/3 + 4/5)*15/4 = 4(1/3+1/5)*15/4 = (1/3+1/5)*15, since the 4's cancel out

2/ 4/15 =15/2 =0.3333

2/(4/15)=2.5

15 divided by 2 is less than 1? You have $15 that you share with your friend and you each get less than $1. Is that because of inflation?


2/ 4/15 =15/2 is NOT correct.

2/(4/15)=2.5 is Not correct.

Eddy, you are trying to study algebra but your arithmetic is simply awful!
