Question 1
1 / -0

The sum of (6 tens 11 tenths and 32 hundredths) and (5 tens 15 hundredths and 38 thousandths) is

A
100.602

B
110.562

C
111.608

D
112.015

Solution

6 tens 11 tenths and 32 hundredths
= 6 x 10 + +
= 60 + 1.1 + 0.32
= 61.42

5 tens 15 hundredths and 38 thousandths
= 5 x 10 + +
= 50 + 0.15 + 0.038
= 50.188

Sum = 61.42 + 50.188 = 111.608

A
28.01

B
24.07

C
28.07

D
25.03

Question 4
1 / -0

What is 8050.329 rounded to the nearest hundredths?

A
8050.33

B
8050.32

C
8050.34

D
8050.3

Solution

When we round the numbers to nearest hundredth, we look at the thousandths place.
In the given number the digit at the thousandths place is 9, which is greater than 5.
Hence we round up the digit at the hundredths place, i.e. 2 becomes 3.
So, 8050.329 rounded to the nearest hundredths is 8050.33
Question 5
1 / -0

Which of the following decimals are arranged in descending order?

C
12.75, 12.72, 13.501

D
11.89, 10.98, 9.631

Solution

When we have to arrange the numbers in descending order, we arrange them from largest to smallest.
Now, the whole numbers are 11, 10 and 9.
11.89 > 10.98 > 9.631

Find the sum of 12 and the difference of 569 hundredths and 3409 thousandths. (Round off the answer up to one decimal place.)

A
14.5

B
14.2

C
14.3

D
14.4

Solution

569 hundredths can be written as:

= 5.69

Similarly,

= 3.409

Difference = 5.69 - 3.409 = 2.281
Sum = 12 + 2.281 = 14.281
Round off your answer up to one decimal place = 14.3
(We have to round it to nearest tenths, and the digit at the hundredths place is 8, which is greater than 5.)
Question 10
1 / -0

Mia uses m of red ribbon instead of every m of yellow color ribbon while decorating a frame. How many red ribbons will she use in place of 1 m yellow ribbon?

A
m

B
m

C
m

D
m

Solution

m of red ribbon = m of yellow ribbon

1 m of yellow ribbon = m of yellow ribbon + m of yellow ribbon + m of yellow ribbon + m of yellow ribbon

Replacing the length of the yellow ribbon with the red ribbon, we get:

1 m of yellow ribbon = red ribbon + red ribbon + red ribbon + red ribbon = red ribbon

A
3.35

B
4.23

C
5.35

D
6.29

Solution

Let the missing number = x

3.25 - 10 x + ( 32.4 ÷ 2) = - x

3.25 - 10 x + 16.2 = - x

3.25 - 22 + 16.2 = - x

3.25 + 16.2 - 22 = - x

19.45-22 = -x.

x = + 22 - 19.45
x = + 2.55

x =

x = 3.35

D
278.1

Solution

We know that 99 tenths = = 9.9
Also,
630 thousandths = = 0.630 = 0.63

Difference = 9.9 - 0.63 = 9.27
Product = 30 x 9.27 = 278.1

Solution

To compare the decimal numbers we start from left hand side.
In option 2, the digit at the ones and tenths place are same.
However, digit at the hundredths place is bigger for the second number.
Hence, only option 2 is correct.

Question 30
1 / -0

Find the value of

(i) 5.8 x A = 245.34

(ii) 1373.36 - 895.36 = B

(iii) C + 2442.86 = 3834.56

A
2

B
3

C
14

D
23

Solution

(i) 5.8 x A = 245.34
A = 245.34 ÷ 5.8
A = 42.3

(ii) 1373.36 - 895.36 = B
B = 478

(iii) C + 2442.86 = 3834.56
C = 3834.56 - 2442.86 = 1391.7

Now,
A + C = 42.3 + 1391.7 = 1434
(A + C) ÷ B
1434 ÷ 478 = 3
