Thx
Thx but how is 7/6 - 10/33 equals 19/22 i don’t get it
Ahh the smallest multiple of both 6 and 33 is 66
So to minus fractions, you need the base to be the same (we change it to 66)
66/6=11 (this is how much u need to multiply the first fraction by)
7/6 x 11/11 = 77/66
For the second fraction, you need to multiply by 66/33= 2
10/33 x 2/2 = 20/66
77/66 - 20/66 = 57/66 (simplify, divide both 57 and 66 by 3) = 19/22
There you go :) hope it helped
