Thank you for the opportunity to help you with your question!

since ratio of orange juice to lemonade is 5: 2 then for every cup of juice there will be

5/(5+2) = 5/7 will be orange juice

2/7 will be lemon juice

in 10 cups orange juice will be

5/7*10 = 7.143 cups will be orange juice

lemon juice will be

2/7 *10 = 2.857 cups

therefore you need 7.143 cups of orange juice and 2.857 cups of lemon juice to make 10 cups
