2/5 xx 2525×25

=10=10

Explanation:

We can work this out by realising that 'fifths' means that a number is broken down into 55 equal parts.

So, One fifth of 1010 would be 10 div 5 = 210÷5=2

1/515 of 3030 would be 30 div 5=630÷5=6

One fifth (1/5)(15) of 2525 would be 25 div 5 = 525÷5=5

Two fifths just means two of the equal parts.

Two fifths of 2525 would be 5+5 = 2 xx 5 = 105+5=2×5=10

Or

2/cancel5 xx cancel25^5

= 2xx5

=10
