The portion of the tank filled in four hours = 67
Q4A person has done 310 of a job in one week. The next week, he is only able to complete 110 of the job. Find the fraction of work he completed in the two weeks.
A. 18
B. 25
C. 16
D. 17

Step: 1
Work done by the person in the first week = 310
Step: 2
Work done by the person in the second week = 110
Step: 3
Total work done by the person in the past two weeks = 310 + 110
Step: 4
3 + 1 = 4
[Denominators are equal. So, add the numerators.]
Step: 5
310 + 110 = 410

Step: 6
410 = 25
[Divide.]
Step: 7
The work done by the person during the two weeks = 25.

Salary spent in the next two weeks = 27
Step: 3
The total part of salary spent in the month = 37 + 27
Step: 4
= 3 + 27 = 57
[Denominators are equal. So, add the numerators.]
Step: 5
Frank spent 57 of the total part of salary in the month.
Q6Justin's mother gave 13 of an apple to him before he left for school. She gave 23 of the apple to him after he returned from school. How much of the apple did he eat in all?

Part of apple given to him after he returned from the school = 23
Step: 3
The part of the apple he got in total = 13 + 23
Step: 4
= (1+2)3
[Denominators are equal.]
Step: 5
= 33 = 1
Step: 6
Justin ate one whole apple.
Correct Answer is :   whole apple
Q7Emily spends 110 of her day playing sports and 310 of her day studying. What fraction of the day does Emily spends together playing sports and studying?

A. 13 of the day

The time Emily spends studying and playing = the time she spends studying + the time she spends playing = 310 + 110.
Step: 2
= 3 + 110 = 410
[As the denominators of the fractions are equal, just add the numerators 3 and 1.]
Step: 3
= 4 ÷ 210 ÷ 2 = 25
[Simplify the fraction by dividing both the numerator and the denominator by 2.]
Step: 4
So, Emily spends 25 of her day studying and playing.
Correct Answer is :   25 of the day

D. 45 cup

Step: 1
Total milk used = Milk used for making one recipe + Milk used for making another recipe = 15 + 15
[Substitute the fractions.]
Step: 2
= (1 + 1)5 = 25
[As the denominators of the fractions are equal, just add the numerators 1 and 1.]
Step: 3
So, Quincy used 25 cup of milk.

Step: 1
The weight of watermelon and pineapple = Weight of watermelon + Weight of pineapple = 711 + 311
Step: 2
= (7+3)11 = 1011
[As the denominators of the fractions are equal, just add the numerators 7 and 3.]
Step: 3
So, the weight of watermelon and pineapple is 1011 pounds.
Correct Answer is :   1011 pounds
Q10Rose bought 63 chocolates. She ate 59 of the chocolates and her friend ate 29 of the chocolates. Find the sum of the fractions of chocolates that Rose and her friend ate.

Sum of the fractions of chocolates = Fraction of chocolates Rose ate + Fraction of chocolates her friend ate = 59 + 29
[Substitute the fractions.]
Step: 2
= (5+2)9 = 79
[As the denominators of the fractions are equal, just add the numerators 5 and 2.]
Step: 3
So, Rose and her friend ate 79of the chocolates .
