Final answer:
To find out which is bigger, we calculate 40% of 210 and 1/4 of 320. 40% of 210 is greater than 1/4 of 320.
Step-by-step explanation:
To find out which is bigger, 40% of 210 or 1/4 of 320, we need to calculate both values.
First, 40% of 210 can be calculated by multiplying 210 by 0.4. This gives us 84.
Next, 1/4 of 320 can be calculated by dividing 320 by 4. This gives us 80.
Therefore, 40% of 210 is greater than 1/4 of 320.
