There are three numbers a, B and C. It is known that one third of a is equal to one fourth of B, and seven eighths of B is equal to seven twelfth of C. It is also known that a is 666 smaller than C, So a =?, B =?, C =?

One third of a is equal to one fourth of B
A is equivalent to (1 / 4) / (1 / 3) = 3 / 4 of B
Seven eighths of B is equal to seven twelfth of C
C is equivalent to (7 / 8) / (7 / 12) = 3 / 2 of B
So B = 666 / (3 / 2-3 / 4) = 888
a=888*3/4=666
c=888*3/2=1332

How much is one third plus one fourth plus one fifth?

Multiply their numerator and denominator by a number to make them have the same denominator
One third to 20 / 60, one fourth to 15 / 60, one fifth to 12 / 60
Add them up to 20 out of 60 plus 15 plus 12
47 out of 60
This is what we can do in the future

How much is one third and one fourth

General division
=(3 × 4) of (1 × 4) + (4 × 3) of (1 × 3)
=4 / 12 + 3 / 12
=12 (4 + 3)
=7 out of 12

If one fifth of a is equal to one ninth of B, then one fourth of a is equal to a fraction of B

If one fifth of a is equal to one ninth of B, then one fourth of a is equal to five 36th of B
