我想問Maths題.題目:「在C=3分之4m+4分之5n+1中,如果m=6,n= -12,求C

C=(5n+1)/[(4m+4)/3]
=[5*(-12)+1]/[(4*6+4)/3]
=(-60+1)/28*3
= -59/28*3
= -177/28

用中文解釋好難明你個問題係咪：C=4m/3 5n/4 1=4*6/3 5*(-12)/4 1=24/3-60/4 1=8-15 1=-6

C=4m/3 5n/4 1=4*6/3 5*(-12)/4 1=24/3-60/4 1=8-15 1=-6

個 係補充度會變空格ge...

C = 4m/3 + 5n+1/4

m=6 n=-12

C= 24/3 + 5(-12)+1/4

C= 8+ -59/4

C= -6.75

sor...睇錯題...C=(5n 1)/[(4m 4)/3]C=(5n 1 / 4m 4 )* 1/3C= -59/28 * 1/3C= -59/84
