5TH GRADE MATH WORKSHEET PRINTABLE

Question 1 :

Two coins contain silver and copper in the ratio 4:5 and 7:15.Which of them contain more silver?

(A) First coin      (B) Second coin        (C) Both of them

Solution :

Ratio of silver to copper in the first coin is 4 : 5

Ratio of silver to copper in the second coin is 7 : 15

By multiplying the first ratio by 3, we get

12 : 15

So, the first coin contains more silver.

Question 2 :

18 mangoes cost $27. What will 15 mangoes cost?

(A) $5.5    (B) $10.5    (C) $22.5

Solution :

Cost of 18 mangoes  =  27

Cost of 1 mango  =  27/18  =  1.5

Cost of 15 mangoes  =  15(1.5)

  =  22.5

Cost of 15 mangoes is $22.5

Question 3 :

A train goes 280 km in 4 hours. How far will it go in 24 hours?

(A)  1320       (B) 1500      (C) 1680

Solution :

Distance covered in 4 hours  =  280 m

Distance covered  =  280/4

  =  70 m

Distance covered in 24 hours  =  24(70)

  =  1680 m

Question 4 :

There are 50 pages in a magazine. 12% of the pages have pictures on them. How many pages of the magazine have no pictures on them?

(A)  50 pages      (B)  44 pages      (C)  30 pages

Solution :

Percentage of pages have no picture  =  100 - 12 

  =  88

Number of pages which have no picture  =  88% of 50

=  (88/100) ⋅ 50

=  44 pages

Question 5 :

John receives $750 a month from his mother. If he spends 55% of it on food, how much does he spend on food?

(A) $505.5       (B) $412.5       (C) $300.5

Solution :

Amount he spent for food  =  55% of 750

  =  (55/100) ⋅ 750

  =  412.5

Question 6 :

Find the simple interest on $3000 at the rate of 4% per annum for 2 years  ?

(A) $240     (B) $300       (C)  150

Solution :

Principal  =  3000

Rate of interest  =  4%

Number of years  =  2

Simple interest  =  PNR / 100

  =  (3000 ⋅ 2 ⋅ 4)/100

  =  240

Hence the required interest is $240.

Question 7 :

Find the average of 4, 10, 18, 8

(A)  25        (B)  50       (C)  64

Solution :

Average of 4, 10, 18, 8 :

  =  (4 + 10 + 18 + 8)/4

  =  40/4

  =  10

Question 8 :

In a class of 55 of pupils, 44 are boys. What percentage of the pupils are girls

(A)  20%        (B) 15%       (C)  30%

Solution :

Total number of students  =  55

Number of boys  =  44

Number of girls  =  55 - 44

  =  11

Percentage of girls  =  (11/55) ⋅ 100%

  =  20%

Question 9 :

What is the next number of the pattern ?

320, 160, 80, 40, _______

(A)  20      (B)  17       (C)  40

Solution :

By observing the sequence, we get every term by dividing the previous term by 2.

So, the next term will be 40/2, that is 20.

Question 10 :

Add 6a + 2a + 8a

(A)  11a       (B) 16a      (C)  12a

Solution :

6a + 2a + 8a

By adding 6, 2 and 8, we get 16. So, the answer will be 16a.
