#2/5# of #25# is #10#

Explanation:

To multiply a fraction by a natural number you have to multiply the numerator by the number and leave the denominator unchanged:

#2/5*25=(2*25)/5=50/5=10#

#2/5 xx 25#

#=10#

Explanation:

We can work this out by realising that 'fifths' means that a number is broken down into #5# equal parts.

So, One fifth of #10# would be #10 div 5 = 2#

#1/5# of #30# would be #30 div 5=6#

One fifth #(1/5)# of #25# would be #25 div 5 = 5#

Two fifths just means two of the equal parts.

Two fifths of #25# would be #5+5 = 2 xx 5 = 10#

Or

#2/cancel5 xx cancel25^5#

#= 2xx5#

#=10#
