Question

Nikitha said compound ratio of 4:5 and 3:5 is 7:10. Do you agree with Nikitha give reason.​

Answer 1

Step-by-step explanation:

No, I don't agree.

because Compounded ratio: For two or more ratios, if we take antecedent as product of antecedents of the ratios and consequent as product of consequents of the ratios, then the ratio thus formed is called mixed or compound ratio. ... For ratios m : n and p : q; the compound ratio is (m × p) : (n × q).

so compound ratio of 4:5 and 3:5 is-

(4*3):(5*5)

= 12:25
