**Multiply.**

Question 3.

Answer:

Step 1: Multiply ones digit of the top number by the ones digit of the bottom number,which is 9Ă—2=18 and carry the 1 over the 1. Now, the unit’s digit will be 8.

Step 2: Now mutiply tens digit of the top number by the ones digit of the bottom number, which is 9Ă—1=9. Now, the tens digit will be 9+1=10. Now, the ten’s digit will be 10.

Final product will be 108

Question 4.

Answer:

Step 1: Multiply ones digit of the top number by the ones digit of the bottom number,which is 5Ă—6=30 and carry the 3 over the 1. Now, the unit’s digit will be 0.

Step 2: Now mutiply tens digit of the top number by the ones digit of the bottom number, which is 5Ă—1=5. Now, the tens digit will be 5+3=8. Now, the ten’s digit will be 8.

Final product will be 80

Question 5.

Answer:

Step 1: Multiply ones digit of the top number by the ones digit of the bottom number,which is 3Ă—5=15 and carry the 1 over the 2. Now, the unit’s digit will be 5.

Step 2: Now mutiply tens digit of the top number by the ones digit of the bottom number, which is 3Ă—2=6. Now, the tens digit will be 6+1=7. Now, the ten’s digit will be 7.

Step 3: Now mutiply tens digit of the top number by the ones digit of the bottom number, which is 3Ă—2=6. Now, the tens digit will be 6. Now, the ten’s digit will be 6.

Final product will be 675

**Add. Write in simplest form.**

Question 6.

\(\frac{2}{10}\) + \(\frac{5}{10}\) = _____________

Answer:

Step 1: As the denominators of the given fraction is same, add the numerators directly.

Step 2: \(\frac{2}{10}\) + \(\frac{5}{10}\) = \(\frac{7}{10}\)

Thus, the sum of \(\frac{2}{10}\) + \(\frac{5}{10}\) equals \(\frac{7}{10}\)

Question 7.

\(\frac{1}{4}\) + \(\frac{1}{4}\) = ______________

Answer:

Step 1: As the denominators of the given fraction is same, add the numerators directly.

Step 2: \(\frac{1}{4}\) + \(\frac{1}{4}\) = \(\frac{2}{4}\)

Simplified fraction will be \(\frac{1}{2}\)

Thus, the sum of \(\frac{1}{4}\) + \(\frac{1}{4}\) equals \(\frac{1}{2}\)

Question 8.

\(\frac{1}{6}\) + \(\frac{3}{6}\) = ______________

Answer:

Step 1: As the denominators of the given fraction is same, add the numerators directly.

Step 2: \(\frac{1}{6}\) + \(\frac{3}{6}\) = \(\frac{4}{6}\)

Simplified fraction will be \(\frac{2}{3}\)

Thus, the sum of \(\frac{1}{6}\) + \(\frac{3}{6}\) equals \(\frac{2}{3}\)

**Write the time shown on each clock.**

Question 9.

Answer:

The small hand indicates hours and the large hand indicates minutes.

The hour hand is at 3 and the minutes hand is at 12.

Therefore, we can say it is 3’o clock.

Question 10.

Answer:

The small hand indicates hours and the large hand indicates minutes.

The hour hand is between 4 and 5. So, we say it as 4 hours.

The minute hand is eaxctly at 3, 3Ă—5=15 minutes.

Therefore, we can say it as 15 minutes past 4.

Question 11.

Answer:

The small hand indicates hours and the large hand indicates minutes.

The hour hand is between 5 and 6. So, we say it as 5 hours.

The minute hand is eaxctly at 9, 9Ă—5=45 minutes.

Therefore, we can say it as 45 minutes past 5 or Quarter to 6.
