Question

If A:B =4:5 and B:C =6:7
Find the continued ratio of A:B:C

Answer 1

$1 )Given \: A : B = 4 : 5 \: --( 1 )$

$and \: B : C = 6 : 7 \: ---(2)$

/* Multiplying equation (1) by 6 and equation (2) by 5 we get */

$A : B = 24 : 30 \: --(3)$

$and \: B : C = 30: 35 \: ---(4)$

$Now, \red{ A : B : C } \green { = 24 : 30 : 35 }$

$2) \red{ Value \: of \: 16+(-13)-(+7)-(-8)} \\= 16 - 13 - 7 + 8 \\= 16 + 8 - 13 - 7 \\=24 - 20 \\= 4$

Therefore.,

$\red{ Value \: of \: 16+(-13)-(+7)-(-8)}\green {= 4}$
