Question

A restaurant owner mixed the juices of 7 lemons with every 3 oranges to make a special drink

Which ratio of lemons to oranges will make the same drink?
a:28:15
b:42:21
c:​21:9
d:15:35

Answer 1

C, 21:19

Explanation:

This is because we know that 21 divided by 7 is 3, so we would have to make sure that we are multiplying 7:3 by 3, which we are because 7 times 3 = 21 and 3 times 3 = 9.
