ksmith67 :

60 years old and I've never had to use that math problem

P.K Ntume :

am still trying to solve you, i will get to the numbers later 😂😂😂

joshua.mcdermid :

Easier to convert to 35/60 - 27/60 + 22/60 and solve for 30/60. Then simplify t0 1/2.

Glendenning Cram :

yes but these are very special cases. what about 5/12-7/20+13/30? her pattern doesn't work. it's much easier with lcd and more generally applicable.

Kandi :

Just find the LCM

yrovi55 :

Convert fractions to decimal and you get 0.5 which equals 1/2

cachaloo :

this reminds me of a teacher who would give the reason for solving a certain way "if you're clever" you do this, which I felt was a bit of "hand waving" , So this method works. But only for special fractions in the form you showed. 😉

נהוראי🥷 :

Here it’s easier to do (35-27+22)/60=30/60=1/2 tho

_ :

Ok, now lets see the simple way

Robert Fontaine 🇨🇦 :

not faster but I love this decomposition

Piece of cake :

jacobiquenteri :

literally this was giving me a headache. I prefer the old way to do math. all this is a headache

Blessed :

your method is complicated

Easy money :

long process.

RG :

3.5/6 - 4.5/10 + 5.5/15 😳😳😳😳😂😂😁😁

socialmedia :

clever 😉

Agustín Montero :

12=2²•3 20=2²•5 30=2•3•5 MCM=2²•3•5=60 (7/12)-(9/20)+11/30)= 35/60-27/60+22/60= 30/60=1/2

Essam M. Amer :

طريقه طويله وأكيد هتلخبط الاطفال واعتقد ان هذه الطريقه ابسط

T4heri :

thanks

Sima :

1/2

Wentok :

34/28

hejhej123471 :

1/2

Pak Deni :

7/ 12 - 9/ 20 + 11/ 30 = 7/12. - 9/ 20 = 140/ 240 - 108/ 240 = 32/ 240. = 4/ 30. 4/ 30 + 11/ 30 = 15/ 30. = 1/ 2 = 50%

Toto Ed :

very nice
