Answer:
Sugar concentration of the mixed soft drink will be <em>32.5%.</em>
<em></em>
Step-by-step explanation:
Sugar concentration of first drink = 20%
Volume of first soda = 250 ml
Sugar in first soda = 20% of 250 ...... (1)
Sugar concentration of second drink = 45%
Volume of second soda = 250 ml
Sugar in second soda = 45% of 250 ...... (2)
Let be the sugar concentration in resultant mixture.
Volume of mixture = 250 + 250 = 500 ml
Sugar in mixture = of 500 ml ...... (3)
Total sugar concentration (Adding (1) and (2)) and equating it to equation (3):
20% of 250 + 45% of 250 = of 500
Hence, Sugar concentration of the mixed soft drink will be <em>32.5%.</em>
Answer:

Step-by-step explanation:
Rate =
But Rate is also equal to number of lawns mowed in a certain amount of time.

If 6/5 lawns are mowed in 1 hour, then,
6 lawns will be mowed in:
=
= 5 hours.
therefore, 6 laws will be mowed in 5 hours.
Ratio of lawns to hours in 6:5
