Which of the following is the best estimate of the number of centimeters (cm) in 2 yards? (Note: 1 yard=3 feet; 1 foot =12 inches; 1 inch =2.54 cm)

A. 175 cm

B. 180 cm

C. 136 cm

D. 90 cm

Answer Explanation:

we convert the given value in yards to the cm by setting up the equation below.

2 yards is equal to 182.88 cm, which is approximately 180 cm.

  • Q #1: Three friends are sharing a pizza. One friend eats half of the pizza. The other two friends equally divide the rest among themselves. What portion of the pizza did each of the other two friends receive?

    A. 1/6

    B. 1/3

    C. ¼

    D. 1/5

    Answer Explanation

     we need to find the portion of pizza shared by two other friends.

    We know that a whole pizza represents 1 and one friend eats half of it. So, the remaining amount left to other two friends is

    Remaining fraction of the pizza=1-1/2=1/2

    Now, the two friends share ½ amongst themselves equally. Then, each friend gets

    The two friends each gets 1/4 of the pizza.

  • Q #2: Simplify the expression below. Which of the following is correct? \(\frac{[3 (2 + 6 \ast 4)]}{(26 \div 2)}\)  

    A. 6

    B. 8

    C. 12

    D. 9

    Answer Explanation

    We follow the order of operations to solve the given expression.

    First, we start with the numerator and solve it as follows

    [3(2+6*4)]

    We start with multiplication in inner brackets, 6*4=24. The expression becomes

    [3(2+24)]

    Then, we conduct the addition of 2+24=26. Then, the expression becomes

    [3(26)]=3*26=78

    Now, we solve for denominator, which is 26/2=13.

    Thus, the expression is reduced into

    \(\frac{[3(2+6\ast4)]}{(26\div2)}=\frac{78}{13}=6\)

    The expression reduces into 6.

  • Q #3: -2/9, -0.9, -1.7, -4/7 Of the number listed above, which number is the greatest?

    A. -0.9

    B. -4/7

    C. -1.7

    D. -2/9

    Answer Explanation

    The initial step is to convert the decimal options to fractions. Then, we find the LCM of the denominators of all fractions, which will be used to compare the values of the given options.

    -0. becomes -9/10

    -1.7 becomes -17/10

    Then, the resulting denominators are 9, 10, and 63. Their LCM of 630 is used to multiply each fraction.

    -2/9*630=-140

    -9/10*630=-567

    -17/10*630=-1071

    -4/7*630=-360

    From the calculations above, -140 is the greatest value of all the values. Thus, -2/9 is the greatest number.
