Please help me and also thanks​

Answer 1

`D.(5)/(3)=(20)/(x)`

Explanation:

`We\ are\ given\ that,\\Ratio\ from\ the\ number\ of\ oranges\ to\ the\ number\ of\ tangerines\ in\ the\ box=5:3=(5)/(3) \\Hence,\\No.\ of\ Oranges\ in\ the\ box=20\\Hence,\\In\ order\ to\ set\ up\ a\ proportion, we\ need\ to\ follow\ the\ equation:\\(x_1)/(y_1)=(x_2)/(y_2) \\`

`Here,\\x_1=Rational\ No.\ of\ oranges\ =5\\y_1=Rational\ No.\ of\ Tangerines\ =3\\x_2=Actual\ no.\ of\ oranges\ =20\\y_2=Actual\ no.\ of\ Tangerines =x\\Hence,\\(5)/(3)=(20)/(x)`
