**5th Grade Math Problems with Answers :**

In this section, we will see some practice problems for 5th grade students.

**Question 1 :**

I have $3 If I spend one-fourth of it, how much money, in dollars, do I have left?

$2.25 (B) $1.50 (C) $1.80

**Solution :**

Money i had = 3

Money spent = 1/4 of 3

= 3/4

Remaining amount i have = 3 - (3/4)

= (12 - 3)/4

= 9/4

= 2.25

Hence the remaining amount is 2.25.

**Question 2 :**

If I am three years younger than Jae, Jae is 5 years younger than Ben, and Ben is 13, how old am I ?

(A) 2 (B) 4 (C) 5

**Solution :**

Age of Ben = 13

Age of Jae = 13 - 5 = 8

Age of me = 8 - 3 = 3

Then i am 3 years old.

**Question 3 :**

The cost of BCA math camp is $50 per student. However, Mrs.Jennifer buys 5 dozen donuts every day for the 16 days. If donuts cost $10 per dozen, how many students need to attend math camp in order for Mrs.Jennifer to break even?

(A) 14 (B) 20 (C) 16

**Solution :**

Cost of donuts that she buy :

5 dozens every day for 16 days.

Quantity of donuts = 5(16)

= 80

Cost of 1 dozen donut = 80 (10)

= 800

More number of students need to attened = 800/50

= 16

Hence 16 is the answer.

**Question 4 :**

Joseph wants a new bicycle. He earns $3 a day for taking out the trash. If the bicycle costs $60, how many days must Joseph take out the trash for ?

(A) 10 (B) 20 (C) 15

**Solution :**

Money he is earning everyday = 3

Cost of bicycle = 60

More number of days he has to work = 60/3

= 20 days

Hence 20 days is the answer.

**Question 5 :**

Calculate 2^{2} - 3^{2} + 4^{2}

(A) 20 (B) 11 (C) 15

**Solution :**

2^{2} - 3^{2} + 4^{2 }

= 4 - 9 + 16

= 20 - 9

= 11

**Question 6 :**

Find the missing term of the following 3 + _________ + 4000 + 60 + 70000 = 74563

(A) 500 (B) 300 (C) 800

**Solution :**

Let x be the missing term

3 + x + 4000 + 60 + 70000 = 74563

74063 + x = 74563

x = 74563 - 74063

x = 500

Hence the missing term is 500.

**Question 7 :**

Find the reduced fraction of the decimal 0.25

(A) 25/100 (B) 1/2 (C) 1/4

**Solution :**

0.25 = 0.25 (100/100)

= 25/100

= 1/4

**Question 8 :**

What is the formula to find the perimeter of rectangle

(A) 2(l + b) (B) l x b (C) 4a

**Solution :**

Perimeter of rectangle = 2(l + b)

**Question 9 :**

Complete the equivalent ratio 3/30 = x/60

(A) 6 (B) 7 (C) 4

**Solution :**

3/30 = x/60

x = (3/30) 60

x = 6

**Question 10 :**

Find the area of the circle which is having the radius 3cm.

(A) 18π^{ }(B) 9π^{ }(C) 15 π

**Solution :**

Area of circle = πr^{2}

r = 3

= π(3)^{2}

= 9π
