It is known that a × 4 / 3 = 11 / 12 × B = 5 / 5 × C, and ABC is not equal to 0. Please arrange the three numbers of ABC in descending order and explain why they are arranged in this way
A×4/3=11/12×B=5/5×C
A=3/4C
B=12/11C
B>C>A
How much is three eighths by one fourth plus five eighths by twenty-five percent?
Life saving
(3/8)*(1/4)+(5/8)*(25/100)
=(3/8)*(1/4)+(5/8)*(1/4)
=[(3/8)+(5/8)]*(1/4)
=1/4
It is known that a × 7 / 8 = B × 7 / 10 = C × 7 / 12, ABC is not equal to 0, so it is necessary to arrange ABC from small to large
7 out of 8 > 7 out of 10 > 7 out of 12
So a
