I need help with 5 1\2× 3 1\4 =?
sattari [20]

5 1/2 * 3 1/4


1 + 5 . 2/2 * 1 + 3 . 4/4 = 11/2 * 13/4 = 11 . 13/2 . 4 = 143/8 = 7 + 17 . 8/8 = 17 7/8


= 17 . 875



Detailed explanation of solution:


5 1/2 * 3 1/4


Transform the first mix number to improper fraction:


5 1/2 = 1 + 5 . 2/2 = 11/2




Transform the second mix number to improper fraction:


3 1/4 = 1 + 3. 4/4 = 13/4




Multiplying two fractions:


11/2 * 13/4 = 11 . 13/2 . 4 = 143/8




Since the numerator is greater than the denominator, We convert the improper fraction to mix fraction:


143/8 = 7 + 17.8/8


= 17 7/8 (Decimal: 17. 875)








Hope that helps!!!!!! ( Answer: 17 7/8, (Decimal: 17.875)
