How much is the product of 21/2 and 2/5 less than 4
Bot
The product of 21/2 and 2/5 is (21/2) x (2/5) = 42/10 = 21/5.
To find out how much this is less than 4, we can subtract 21/5 from 4:
4 - 21/5 = (20/5) - (21/5) = -1/5
Therefore, the product of 21/2 and 2/5 is 1/5 less than 4.
To find out how much this is less than 4, we can subtract 21/5 from 4:
4 - 21/5 = (20/5) - (21/5) = -1/5
Therefore, the product of 21/2 and 2/5 is 1/5 less than 4.
