1328
1528
1315
515

Discuss Question

Answer: Option B. -> 1528
:
B
Number of flowers in Simon's garden = 28
Number of flowers that wilted = 13
Number of flower that are still blooming =Total number of flowers - Number of flowers that wilted
Number of flowers still blooming = 28 - 13 = 15
The fraction of flowers that are still blooming =

\frac{15}{28}

Question 3. What fraction of natural numbers from 2 to 10 are prime numbers?

Discuss Question

Answer: Option D. -> 49
:
D
Natural numbers from 2 to 10are: 2, 3, 4, 5, 6, 7, 8, 9, 10
Number of Natural numbers from 2 to 10= 9
Prime numbers from 2 to 10: 2, 3, 5, 7
Number of Prime numbers from 2 to 10= 4
Hence, the fraction of prime numbers from 2 to 10=

\frac{4}{9}

Question 4. What should be the size of piece that would fit in the unknown region?

Discuss Question

Answer: Option A. -> 112
:
A

\frac{3}{4} + \frac{1}{6}

To add the 2 fractions, we need to find the LCM of 4 and 6

LCM of 4 and 6 = 12

\frac{3}{4} + \frac{1}{6} = \frac{3 \times 3}{4 \times 3} + \frac{1 \times 2}{6 \times 2} = \frac{9 + 2}{12} = \frac{11}{12}

To find the missing piece,

= 1 - \frac{11}{12} = \frac{12 - 11}{12} = \frac{1}{12}

Question 5.

8.25 - \frac{23}{100}

= ______

3.62
0.38
8.02
0.52

Discuss Question

Answer: Option C. -> 8.02
:
C
Convert

\frac{23}{100}

into decimal
8.25 - 0.23 = 8.02

So, they ran for 6.25 miles per day for 25 days.

Question 7. What fraction does the unshaded portion represent?

Discuss Question

Answer: Option D. -> 59
:
D
The given figure is divided into 9 equal parts of small triangles out of which 5are unshaded.
Hence, the fraction representing the unshaded portion is

\frac{5}{9}

Question 8. On arranging the following fractions

\frac{4}{9}, \frac{7}{9}, \frac{1}{9}, \frac{3}{9}

in ascending order we get:

Discuss Question

Answer: Option B. -> 19
:
B
The given fractions are like fractions because all of them have the same denominator, which is 9.
To arrange the following fractions in ascending order we need to arrange their numerators in ascending order.
1 < 3 < 4 < 7

∴ \frac{1}{9} < \frac{3}{9} < \frac{4}{9} < \frac{7}{9}

Question 9.

What is the fraction of the unshaded part?

Discuss Question

Answer: Option A. -> 714
:
A
In the figure given above, there are 14 small triangles out of which 7 are unshaded.
Hence, the fraction can be represented by the unshaded portion =
