Question

what term should be added to antecedent and subtracted from consequent of ratio 4:7 to make a compound ratio of 2:3 and 5:4​

Answer 1

Answer:

Step-by-step explanation:

The compound ratio of 2:3 &5:4. is =

2×5:3×4 =10:12

We know in a:b ratio ,a is antecedent and b is consequent.

So,let the number added or subtracted be a,then

(4+a)÷(7-a)= 10÷12

or 48+12a=70-10a

or 48-70=-10a -12a

or -22= -22a

or a= -22÷ -22

or a=1

So,the number added or subtracted is 1.
