Dominique wants to use the distributive property to find the value of 15⋅37 15⋅63

Distributive law/property is represent as ; a x (b + c) = a x b + a x c

Here a = 15

b = 37

c = 63

So the numbers given in the question can be rewritten as;

15 x (37 + 63) = 15 x 37 + 15 x 63 = 555 + 945 = 1500

so, converting firstly the mixed fractions to improper fractions and then "adding".
