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)

a_sh-v [17]

Answer:

\mathrm{C.\:}25

Step-by-step explanation:

Notice how each congruent square is divided into four equal parts. Since each square has four parts and there are four squares, there are 16 of these parts in total. Because each of these parts make up \frac{1}{4} of each square, all parts are equal. Therefore, you can count the total number of shaded parts to get your percentage.

The top left and bottom right both have one part shaded each for a total of 2 parts.

The top right and bottom left have 0.5 and 1.5 parts shaded, respectively, for a total of 2 parts.

Therefore, in total, there are 2+2=4 parts shaded out of 16 total parts.

Thus, the percentage of the total area that is shaded is:

\frac{4}{16}=\frac{1}{4}=\fbox{$25\%$}.
