(A)  630    (B)  2520    (C)  3060    (D)  3120

Problem 9  :

Jose walker as a dog walker. He charges fifteen dollars per dog and each day he walks eight dogs. How much would he earn in seven days ?

(A)  630    (B)  720    (C)  750    (D)  840

Problem 10  :

Jeremy had to deliver mail to 65 houses on his route. Each house received 12 letters. How many letters did he deliver ?

(A)  662    (B)  715    (C)  780    (D)  795

(1)  Solution  :

We use a number line to fraction order for values between 0 and 1

Since 0  =  0/12, and 1/6  =  2/12

A  =  1/12, then B  =  3/12 by simplifying we get 1/4.

(2)  Solution  :

We order from the point on the given number line.

So, C is the point on the number line 0.59

(3)  Solution  :

Given

0.25, 1/3, 2/5, 0.3

Arrange the given numbers from smallest to largest,

So,  0.25, 0.3, 1/3, 2/5    

Since, 1/3 = 0.3 and 2/5 = 0.4

Therefore, Option (B) is correct.

(4)  Solution  :

Take all given fraction options to find which one is equal to repeating decimal 0.666…

First,

Option (A)  1/6  =  0.1666

Option (B)  6/10  =  0.6

Option (C)  66/100  =  0.66

Option (D)  2/3  =  0.66666

So, Option (D) is equal to repeating decimal 0.6666…

(5)  Solution  :

Factors of 54 : 1, 2, 3, 6, 9, 18, 27, 54

Factors of 12 : 1, 2, 3, 4, 6, 12

Therefore, the G.C.F of 54 and 12 is 6 

(6)  Solution  :

Here, to find the factors but in prime numbers,

60  =  6×10     [ But 6 and 10 are not prime numbers ]

Find factors of 6 and 10,

6  =  2×3

10  =  2×5

So, 60  =  2×3×2×5

Arrange the ascending order,

Prime factors of 60  =  2×2×3×5

Therefore, 2²×3×5 

(7)  Solution  :

Given, 2⁵+3²

2⁵  =  2×2×2×2×2  =  32

3²  =  3×3  =  9

So, 2⁵+3²  =  41

(8)  Solution  :

Given,

Each roses petals  =  35 petals

Total roses  =  72 roses

We find total petals in the roses.

Total petals  =  Total roses × Each roses petals

Total petals  =  72×35

Total petals  =  2520

Therefore, 2520 petals.

(9)  Solution  :

Given,

One dog charges  =  $15

Each day he walks  =  8 dogs

We find how much he earn in seven days ?

Each day charges  =  One dog charges × Each day he walks

=  15×8

=  120

Each day charges  =  $120

So, Seven days  =  Each day charges × Seven days

=  $120×7

=  $840

Therefore, he earn in seven days $840 

(10)  Solution  :

Given,

Total houses  =  65 houses

Each house received  =  12 letters

We find, how many letters he deliver

Total letters  =  Total house × Each house received letters

=  65×12

=  780

Therefore, he deliver 780 letters.
