Show (2.3)(5.06) as a fraction multiplication problem
HACTEHA [7]
2.3 would be 2+(3/10), which we would then use a common denominator of 10 to get 20/10+3/10=23/10. 5.06 would be 5+(6/100). 6/100 can be reduced by a factor of 2 to 3/50, which we would then use a common denominator of 50 to get 250/50+3/50=253/50. As a fraction multiplication problem, this would look as (23/10)(253/50)
