First: make the mixed fraction an improper fraction > multiply the whole number by the denominator and add the result to the numerator and place the new result over the original denominator...
2*2 = 4
4 + 1 = 5
> 5/2
(5/2) * (3/5)
Sec: multiply the numerators and denominators...
(5*3)/(2*5)
15/10
Third: simplify the fraction into lowest terms, if possible...
3/2

2 1/2 x 3/5=5/2 x 3/5.
numerator x numerator over denominator x denominator.
5 x 3=15.
2 x 5=10.
so the answer is 15/10, or 1 1/2.

2 1/2 as a proper fraction is 5/2
so 5/2 x 3/5 is the qn
since we have 5 in the numerator and the denominator we can cancel them and we get 3/2
answer is 1.5

2 1/2= 5/2 5/2x3/5=15/10 or 1 1/2. just multiply the numerators, and denominators together. formula is n x n/d x d=product

2 and 1/2 equales to 5/2
so to do 5/2 multiplied by 3/5 you can just multiply top and bottom
5 x 3
-------
2 x 5
so 5 x 3 = 15
-------------------
and 2x5 = 10
So the answer would be 15/10
You simplify that and you get 1 and 1/2 :-D

2 1/2 * 3/5
= 5/2 * 3/5 [convert 2 1/2 into fractional form]
= 15/10 [mult of fractions is (num1*num2)/(denom1*denom2)]
= (3*5)/(2*5) [simplify common factor]
= 3/2 [remove common factor]
= 3/2 or 1.5
