Answer:
41 or 47
Explanation:
First, list all the prime numbers from 40 to 60.
They are 41, 43, 47, 53 and 59.
It says the difference between each digit is 3, so we have to subtract the smaller digit from the larger digit in our list of prime numbers above.
4-1=3
4-3=1
7-4=3
5-3=2
9-5=4
Both 41 and 47 have a difference of 3 between their digits. So your answer is 41 or 47.

Each board is (4/25) meters long = 0.16 meters long
Step-by-step explanation:
The board is 4/5 meters long, and he needs to cut 5 equal pieces, so we need to divide 4/5 of a meter in 5 parts.
This mathematically becomes: 4/5 divided by 5 which by the definition of division of rational numbers, is the same as :
4/5 times the reciprocal of 5 = (4/5) * (1/5) = (4/25) = 0.16 meters each board
