Question

3 3 over 9 cross times 1 1 third

  1. 2 over 27
  2. 3 over 27
  3. 1 third
  4. 40 over 9

hintHint:

convert the mixed fractions into improper fractions.

The correct answer is: 40 over 9


    3 3 over 9 equals fraction numerator 9 cross times 3 plus 3 over denominator 9 end fraction equals fraction numerator 27 plus 3 over denominator 9 end fraction equals 30 over 9 equals 10 over 3
1 1 third equals fraction numerator 1 cross times 3 plus 1 over denominator 3 end fraction equals 4 over 3
10 over 3 cross times 4 over 3 equals 40 over 9

    Lets convert the mixed fractions into improper fractions. We get ((9 x 3) +3)/9 and ((3 x 1)+ 1)/3, i.e., 30/9 and 4/3. Let’s calculate the product 30/9 x 4/3 . we get 40/9

    Steven calculated the area of a square to be 1 over 81 square yard. What is the side length of the square?


    Given, area of square = 1/81 sq yard. This means that the square of side length is 1/ 81. This means that we need to find the square root of 1/ 81. Square root of 1 is 1.  To find the square root of 81, let’s find the factors of 81.  By using hit and trial method, we can write that 81 = 3 x 3 x 3 x3 = 9 x 9. Hence, 9 is the square root of 81. Hence, our required answer is 1/9 , which is the square root of 1/81.

    Irene buys a talking doll for $11.66 and batteries for $3.22. She pays with a $30 bill. Estimate how much change she should get ?

    Cost of doll=$ 11.66
    Cost of batteries =$ 3.22
    Total cost = 11.66 + 3.22 =$ 14.88
    Amount paid = $ 30
    Amount to be returned = $ 30- total cost= $30 - $ 14.88= $ 15.12$
