Step 2: Now mutiply tens digit of the top number by the ones digit of the bottom number, which is 5×1=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 3×5=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 3×2=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 3×2=6. Now, the tens digit will be 6. Now, the ten’s digit will be 6.
Final product will be 675

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, 3×5=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, 9×5=45 minutes.
Therefore, we can say it as 45 minutes past 5 or Quarter to 6.
