Answer: 37
Step-by-step explanation: To find 25% of 148, first write 25% as a decimal by moving the decimal point two places to the left to get .25 which is the decimal equivalent to 25%.

(.25) (148) = 37
Therefore, 37 is 25% of 148.

Answer:
4 and 40
Step-by-step explanation:
2/5 of 10 is 4
2/5 of 100 is 40
Let <em>x</em> be the amount of salt in the solution.
At day's end, the concentration of salt in the beaker is
<em>x</em> / (4 L) = 0.08 = 8%
Solve for <em>x</em> to get
<em>x</em> = 0.08 (4 L) = 0.32 L
So at the beginning, the concentration of salt in the beaker was
(0.32 L) / (5 L) = 0.064 = 6.4%
