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)

Round 7.76 to one decimal place
Gelneren [198K]
So if a number is 5 or greater you round up but if the number is 4 or less you round down so the number 6 is above five so you would round the 6 to 10 therefore making it 7.8 instead of 7.76

My brainy brother and sister added their ages together and got 15. When they multiplied their ages together, they got 54. How ol
Vinvika [58]

Given:

Sum of ages of brother and sister = 15

Product of their ages = 54

To find:

How old is the older one between the two of them?

Solution:

Let x be the age of brother and y be the age of sister.

Sum of ages of brother and sister = 15

x+y=15

x=15-y                ...(i)

Product of their ages = 54

xy=54

(15-y)y=54                [Using (i)]

15y-y^2=54

0=54-15y+y^2

Splitting the middle term, we get

54-15y+y^2=0

54-9y-6y+y^2=0

9(6-y)-y(6-y)=0

(6-y)(9-y)=0

Using zero product property, we get

(6-y)=0\text{ and }(9-y)=0

y=6\text{ and }y=9

If y=6, then using (i), we get

x=15-6

x=9

If y=9, then using (i), we get

x=15-9

x=6

Therefore, the age of older one is 9, the age of younger one is 6 and the difference between their ages is 3.
